d6cc0b4fea conformtest: Fix pselect expectations. 
conformtest expected pselect for XOPEN2K and POSIX2008 (correctly),
but not for XOPEN2K8 (wrongly).  This patch fixes the data to expect
it for XOPEN2K8 as well.

(As for all such fixes based on failures seen from the tests, there is
no guarantee that the data is fully correct for a particular standard
after the fix; headers and data may well have matching bugs.  So far
I've only reviewed ISO, ISO99, ISO11 and POSIX data in detail, though
I hope eventually to review the others.)

Tested for x86_64 and x86.

	* conform/data/sys/select.h-data [XOPEN2K8] (pselect): Expect.
	* conform/Makefile (test-xfail-XOPEN2K8/sys/select.h/conform):
	Remove variable.

5675961d15 conformtest: Support xfail markers on individual assertions. 
Various conformtest tests fail because of known issues, filed in
Bugzilla, that are hard to fix (requiring new features, kernel
cooperation or involving changing types in ways that may involve care
around padding when interfacing to the kernel).  Such an issue has the
effect of making the whole test for the (standard, header) pair fail,
so hiding any other issues with that header for that standard
(possibly regressions or architecture-specific issues).

This patch adds a mechanism for individual conformtest test
expectations to start with xfail-, meaning that a failure of that
particular assertion does not cause the whole test to fail at the
makefile level and so failure at the makefile level can be used to
detect other issues that are likely to be easier to fix.  This is
similar to the whitelisted symbols in the linknamespace tests, or the
marking of particular libm tests as allowing spurious or missing
exceptions, for example.  The bugs filed in Bugzilla should still be
fixed, and the xfail- markers removed at that point, but xfail-
renders the tests more useful until that happens.

Note that there is no way to add such a marker for the assertion that
a header uses only symbols in the namespace of symbols it's meant to
use.  I don't think there's any need for a way to xfail those
namespace tests other than xfailing the whole (standard, header) pair
at the makefile level, since they are generally straightforward to fix
(add appropriate conditionals on the problem definitions).

The xfails in this patch do not necessarily cover all cases of
hard-to-fix header bugs filed in Bugzilla that currently show up in
conformtest failures; there may be more yet to add for existing open
bugs.

Tested for x86_64 and x86.

a7a3c24632 Remove include/bits/ipc.h. 
Ten conformtest failures arise from the internal header
include/bits/ipc.h failing to condition internal declarations, outside
the public namespace of headers including bits/ipc.h, on [!_ISOMAC].
As discussed in
<https://sourceware.org/ml/libc-alpha/2015-06/msg00653.html>, the
internal declarations that are actually relevant are in ipc_priv.h and
so include/bits/ipc.h should not be needed at all; this patch removes
it.  (Ten further conformtest failures for other headers including
bits/ipc.h remain because of other conformance issues in those
headers.)

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

d1ac55d890 Fix netinet/in.h MCAST_* namespace (bug 18558). 
sysdeps/unix/sysv/linux/bits/in.h (as included in netinet/in.h, and
via that in netdb.h and arpa/inet.h) defines a series of MCAST_*
macros, both under __USE_MISC and then again unconditionally.  These
are not POSIX macros, nor in any of the namespaces listed in POSIX as
reserved for this header, so should not be defined unconditionally.
This patch duly removes the unconditional definitions, leaving the
ones conditional on __USE_MISC.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

c362135134 Fix nice getpriority, setpriority namespace (bug 18553). 
nice (XPG3) calls getpriority and setpriority (in XPG4 but not XPG3,
i.e. UX-shaded in XPG4).  This patch fixes this by making those
functions into weak aliases of __* functions and calling the __*

0595c98494 Fix mq_notify socket, recv namespace (bug 18546). 
mq_notify (in the 1996 edition of POSIX) brings in references to recv
and socket (not in POSIX until the 2001 edition).  This patch fixes
this by using __recv and __socket, exporting them from libc at version
GLIBC_PRIVATE.

stripped shared libraries; PLT / dynamic symbol table changes render
the comparison not particularly useful for libc).

45dcd79f6e Fix swscanf vswscanf namespace (bug 18542). 
swscanf (added in C90 Amendment 1, present in UNIX98) calls vswscanf
(added in C99, not in C90 Amendment 1 or UNIX98).  This patch fixes
this by using __vswscanf instead and making vswscanf into a weak
alias.

(I intend to add conform/ test support for C90 Amendment 1 - and
various other standard versions supported by glibc but not yet by
conform/ tests - at some point, once the results for currently tested

The sem_* functions bring in references to tdelete, tfind, tsearch and

a97e5e2557 Fix vsyslog namespace (bug 18533).

alias to a weak alias.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).  (vsyslog becomes weak
in the static libraries, which is what's needed; the particular macro
sequence in use leaves it as strong in the shared libraries, hence
those libraries being completely unchanged, but it doesn't generally
matter whether symbols exported from the shared libraries are weak or
strong.)

17c199ee92 Fix gethostbyaddr in6addr_any, in6addr_loopback namespace (bug 18532). 
gethostbyaddr brings in references to in6addr_any and thereby

gethostbyaddr (gethostbyaddr is in XPG4 and UNIX98, in6addr_any and
in6addr_loopback are new in POSIX.1:2001).  This patch fixes this by
making those symbols into weak aliases (safe in this case, unlike for
most data symbols, because these data symbols are const).

Tested for x86_64 and x86 (testsuite, and comparison of disassembly of

bf1435783d Fix linknamespace expectations for in6addr_any, in6addr_loopback. 
Some linknamespace test failures turned out to be because the
variables in6addr_any and in6addr_loopback weren't listed in the lists
of extra reserved symbols for the relevant standards (only functions
are handled automatically through -aux-info, data symbols need listing
manually in list-header-symbols.pl).  This patch duly adds those
symbols to those lists (there are still failures for older standards
because of references to those symbols being brought in for standards
that didn't reserve them: bug 18532, to be fixed separately).

edition of POSIX, non-XSI).  However, the 2013 Technical Corrigendum
corrected the grp.h specification to XSI-shade these functions as in
previous editions (see <http://austingroupbugs.net/view.php?id=24>),
so they should not be declared for non-XSI POSIX.  This patch corrects
the conditions - using __USE_MISC || __USE_XOPEN_EXTENDED to match
setgrent - and the conform/ test expectations for this header, thereby
fixing the conform tests for this header for XPG3 (where the
expectations were wrong) and the linknamespace tests for it for
POSIX2008 (where the header bug meant it was wrongly considered a
problem for endgrent to bring in a reference to setgrent).

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

5371d99e87 Fix getlogin_r namespace (bug 18527). 
Various functions in XPG4 bring in references to getlogin_r, which is
not in XPG4; this is also a bug for some older POSIX versions which
aren't yet covered by the linknamespace tests.  This patch fixes this

9714012ca0 Fix aio_* pread namespace (bug 18519). 
aio_* bring in references to pread, which isn't in all the standards
containing aio_* (as a reference from one library to another, this is
a bug for dynamic as well as static linking).  This patch fixes this
by using __libc_pread instead, exporting that function from libc at
symbol version GLIBC_PRIVATE; the code, with conditionals that may
call either __pread64 or __libc_pread, becomes exactly analogous to
that elsewhere in the same file that may call either __pwrite64 or
__libc_pwrite.

Tested for x86_64 and x86 (testsuite, and comparison of disassembly of
installed shared libraries).  libc changes because of the PLT entry
for the newly exported __libc_pread; librt changes because of
assertion line numbers and PLT rearrangement; other stripped installed
shared libraries do not change.

The functions ecvt, fcvt and gcvt, in some standards, bring in

standards.  The calls are correctly to __ecvt_r and __fcvt_r, but then
the names ecvt_r and fcvt_r are defined as strong aliases; this patch

9acacaa02f Fix h_errno namespace (bug 18520). 
The 2008 edition of POSIX removed h_errno, but some functions still
bring in references to the h_errno external symbol.  As this symbol is
not a part of the public ABI (only __h_errno_location is), this patch
fixes this by renaming the GLIBC_PRIVATE TLS symbol to __h_errno.

Tested for x86_64 and x86 (testsuite, and comparison of installed
shared libraries).  Disassembly of all shared libraries using h_errno
changes because of the renaming (and changes to associated TLS / GOT
offsets in some cases); disassembly of libpthread on x86_64 changes
more substantially because the enlargement of .dynsym affects
subsequent addresses.

open_memstream is new in the 2008 edition of POSIX.  However, the

Tested for x86_64 and x86 (testsuite, and that disassembly of

produce an XPASS for conform/POSIX/unistd.h/linknamespace after this

007f2dd122 Fix psignal, psiginfo declaration conditions (bug 18483). 
signal.h declares psignal and psiginfo if __USE_XOPEN2K - that is, for
the 2001 edition of POSIX.  These functions were actually added in the
2008 edition (as indicated in the header comments).  This patch fixes
the header conditionals.  This fixes some linknamespace test failures
because psiginfo uses fmemopen, which is also new in the 2008 edition,
so before the header fix this appeared to the linknamespace tests as a
2001 function bringing in references to a 2008 function.  The problem
also appeared in conformtest header namespace test results (the
conformtest data has correct conditionals for when these functions
should be visible), but the affected headers still have other
namespace problems so this doesn't fix any of those XFAILs.

POSIX), resulting in linknamespace test failures.  (This is contrary
to glibc conventions, rather than a standards conformance issue,
because of the str* reservation.)  This patch fixes this in the usual

4e5f9259f3 Restore _POSIX2_C_VERSION definition (bug 438). 
My review of conformtest expectations for POSIX showed up that the
_POSIX2_C_VERSION macro, required by POSIX and XPG standards before
2001, was missing in unistd.h, having been removed on 2003-04-03
despite those standards still being supported.  This patch adds it
back.  As it's in the implementation namespace, there's no need for it
to be conditional, and other such macros aren't conditional in this
header either.

The POSIX function scandir calls scandirat, which is not a POSIX

1a2325c06c Fix posix_spawn getrlimit64 namespace (bug 17991). 
posix_spawn (a standard POSIX function) brings in a use of getrlimit64
(not a standard POSIX function).  This patch fixes this by using
__getrlimit64 and making getrlimit64 a weak alias.

This is more complicated than some such changes because of files that
define getrlimit64 in their own way using symbol versioning after
including the main sysdeps/unix/sysv/linux/getrlimit64.c with a
getrlimit macro defined.  There are various existing patterns for such
cases in glibc; the one I've used here is that a getrlimit64 macro
disables the weak_alias / libc_hidden_weak calls, leaving it to the
including file to define the getrlimit64 name in whatever way is
appropriate.

Tested for x86_64 and x86 that installed stripped shared libraries are
unchanged by this patch.

b8986484e4 Fix isblank / isascii / toascii namespace (bug 17635). 
Use of isblank brings in isascii and toascii, but isblank is a C99
function and the other two aren't; similarly, isascii and toascii are
UNIX98 functions and bring in isblank, which isn't.  (Not a
conformance issue because of the is* and to* reservation, but still
contrary to glibc practice.)  This patch fixes this by splitting
isblank out of ctype-extn.c to a separate ctype-c99.c.  isblank_l is
also moved to a separate file, ctype-c99_l.c (non-XSI POSIX.1-2008 has
isblank_l, but isascii / toascii are marked OB XSI).  (In principle
all these functions could go in separate files - that's optimal for
static linking - but they are also all very small, and splitting them
all out is not needed to fix the present bug.)

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch - the ordering in which new and
existing sources are listed in ctype/Makefile is arranged so functions
go in the same order so that this comparison works).

2cfbdb9a27 Fix strftime wcschr namespace (bug 17634). 
Use of strftime, a C90 function, ends up bringing in wcschr, which is
not a C90 function.  Although not a conformance bug (C90 reserves
wcs*), this is still contrary to glibc practice of avoiding relying on
those reservations; this patch arranges for the internal uses to use
__wcschr instead, with wcschr being a weak alias.  This is more
complicated than some such patches because of the various IFUNC
definitions of wcschr (which include code redefining libc_hidden_def
in a way that involves creating __GI_wcschr manually and so also needs
to create __GI___wcschr after the change of internal uses to use
__wcschr).

IS_IN (libc) conditional in rec_hconf.c is needed because that file is
also used in nscd.)

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch except for an assertion line
number).  Note that most of the linknamespace tests that failed
because of fgets_unlocked from the resolver also fail because of other
symbols brought in by the resolver, so the number of XFAILs this
removes is limited.  Also note that fgets_unlocked failures for
unistd.h for XPG3/XPG4 showed up that actually unistd.h is declaring
too much for XPG3/XPG4 (bug 17665) - there is no actual need to make
getusershell.c use __fgets_unlocked (at least as regards formal
standards are concerned; maybe it should still change for
namespace-cleanness of _DEFAULT_SOURCE) because the functions there
aren't actually in any of the supported standards; the correct fix for
those failures will be to stop the *usershell* functions appearing in
unistd.h for XPG3/XPG4.

0e7e69baa8 Make linknamespace tests check only relevant libraries. 
This patch addresses one known caveat in the linknamespace tests: with
this patch they will now only look for definitions of symbols in
relevant libraries, meaning that librt and libpthread are not checked
for ISO C standards, XPG3 and XPG4.

In particular, this means that if __pthread_initialize_minimal is
somehow brought in for one of those standards, the definition from
libc-tls.o will be considered instead of that from libpthread, so
avoiding bringing in lots of other libpthread symbols.  This should
address some of the failures reported by Carlos in
<https://sourceware.org/ml/libc-alpha/2014-11/msg00882.html>, where
__pointer_chk_guard_local brought in __pthread_initialize_minimal.

Tested for x86_64.  The removal of one XFAIL for XPG4 actually shows
up a header bug (shm_open should not be declared for XPG4 - the
namespace issue was for symbols brought in by shm_open, which is no
longer found at all now librt isn't searched; I've filed bug 17663 for
the header bug, though it would show up eventually anyway in the
course of review of conform/ data against XPG4).

9744496f8a Fix perror fileno namespace (bug 17633). 
perror, an ISO C function, uses fileno, which is not an ISO C
function.  This patch makes it use __fileno instead.  (The nearby call
to fdopen is not a problem because that's #defined to _IO_new_fdopen.)

a473381208 Only declare __sigpause in installed signal.h when necessary. 
This patch makes the installed signal.h declare __sigpause only when
necessary (when a macro definition of sigpause makes use of
__sigpause), rather than unconditionally.  This fixes false positives
in the linknamespace tests by making it visible to those tests that no
use of ISO C functionality will actually bring in the definition of
__sigpause and so bring in the other symbols defined in the same
object.  There is no bug filed in Bugzilla because this is fixing
false positives rather than any user-visible bug.

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by this patch).

24f4f8253f Add tests for namespace for static linking. 
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.

This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests).  The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option.  The following comment from
linknamespace.pl explains the caveats around this approach:

Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards).  (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

a75d3b0288 conformtest: clean up POSIX expections for sys/utsname.h, sys/wait.h. 
Continuing the series of patches to clean up conformtest expectations
for "POSIX" (1995/6) based on review of the expectations against the
standard, this patch cleans up expectations for sys/utsname.h and
sys/wait.h.  Tested x86_64; a new XFAIL for sys/wait.h is added.

e59252a58e Define TSVTX in tar.h for older POSIX (bug 16978). 
As noted in bug 16978, older POSIX versions include

in the specified contents of <tar.h>, with only the 2001 edition
introducing the notion of XSI-conditional definitions and conditioning
that definition.  Thus, this macro should be defined for
!__USE_XOPEN2K as well as for __USE_XOPEN, and this patch duly defines
it in that case.  Tested x86_64.

	* posix/tar.h [!__USE_XOPEN2K] (TSVTX): Define macro.

5c7808498e Fix POSIX namespace for <bits/siginfo.h> (bug 16674). 
<bits/siginfo.h> causes symbols ILL_*, FPE_*, SEGV_* BUS_*, CLD_*,
POLL_* and TRAP_* to be exposed in <signal.h> (and <sys/wait.h>), even
though those symbols are not in non-XSI POSIX before POSIX.1-2008 and
even in POSIX.1-2008 the TRAP_* symbols are XSI-only.  This patch
conditions the symbols appropriately in the various <bits/siginfo.h>
implementations (various <signal.h> and <sys/wait.h> conformtest
issues remain for standards other than POSIX (1995/6)).  Tested

bc61d27c61 Include all of <time.h> from <sched.h> for older standards (bug 16670). 
This patch fixes one of the header namespace issues shown up by
conformtest, <sched.h> failing to expose all symbols from <time.h> as
required by older standards.  The patch keeps the existing behavior if
__USE_XOPEN2K is defined (the default; POSIX.1-2001 was the version
that made it optional to expose these symbols), but ensures that all
the symbols from <time.h> are exposed if an older standard is
selected.  Tested x86_64.

54ee292da7 conformtest: split up running of tests from makefile. 
This patch changes the logic by which header conformance tests are run
so that the makefiles run the tests for each (standard, header) pair
separately rather than as a single test (there are 518 such pairs
being tested at present).

Since these tests are slow and previously couldn't be run in parallel,
this obviously speeds up the whole test run significantly when using
parallel testing.  There are other benefits.  These tests can now be
marked as expected to fail at the level of (standard, header) pairs,
meaning that regressions introduced by a header change are much more
likely to be spotted (of course, such a regression could be a bug in
the header or in the expectations, most of which have not been
properly checked against the relevant standards).

The patch introduces lists in conform/Makefile of the headers to test
for each standard, with a new (quick) test for each standard that the
list agrees with the set of headers for which there are in fact
nonempty expectations for that standard.  This means that each of the
518 pairs being tested is actually something meaningful to test rather
than a null test.  I also hope to use these lists of headers in
various standards in future tests for namespace violations where a
function in a standard is implemented to call a non-reserved name for
a function outside that standard.

Although there are a lot of tests now marked as expected to fail, I
expect most of those to be easy to fix (whether with fixes to the
expectations, the headers or both - if fixing a header bug, of course
file it in Bugzilla first); only a limited number are likely to
reflect actual missing features in glibc.

Tested x86_64 (GCC 4.7 branch).  It's quite possible some failures
vary from platform to platform, in which case either additional XFAILs
can be added here, or platform-specific header bugs (if applicable)
the failures show up can be fixed.  I made XFAILs unconditional for
tests that should only fail for GCC 4.6 and earlier; we could make the
GCC version available in the makefiles and condition these, but simply
moving the XFAILing to a finer granularity seems a clear improvement
on the previous state of the whole of conformtest being XFAILed.

f214606a0e Enumerate tests with special rules in tests-special variable. 
This patch is a revised and updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html>.

In order to generate overall summaries of the results of all tests in
the glibc testsuite, we need to identify and concatenate the files
with the results of individual tests.

Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this.
However, the normal glibc approach is explicit enumeration of the
expected set of files with a given property, rather than all files
matching some pattern like that.  Furthermore, we would like to be
able to mark tests as UNRESOLVED if the file with their results is for
some reason missing, and in future we would like to be able to mark
tests as UNSUPPORTED if they are disabled for a particular
configuration (rather than simply having them missing from the list of
tests as at present).  Such handling of tests that were not run or did
not record results requires an explicit enumeration of tests.

For the tests following the default makefile rules, $(tests) (and
$(xtests)) provides such an enumeration.  Others, however, are added
directly as dependencies of the "tests" and "xtests" makefile
targets.  This patch changes the makefiles to put them in variables
tests-special and xtests-special, with appropriate dependencies on the
tests listed there then being added centrally.

Those variables are used in Rules and so need to be set before Rules
is included in a subdirectory makefile, which is often earlier in the
makefile than the dependencies were present before.  We previously
discussed the question of where to include Rules; see the question at
<https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a
discussion in
<https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why
Rules is included early rather than late in subdirectory makefiles.

It was necessary to avoid an indirection through the check-abi target
and get the check-abi-* targets for individual libraries into the
tests-special variable.  The intl/ test $(objpfx)tst-gettext.out,
previously built only because of dependencies from other tests, was
also added to tests-special for the same reason.

The entries in tests-special are the full makefile targets, complete
with $(objpfx) and .out.  If a future change causes tests to be named
consistently with a .out suffix, this can be changed to include just
the path relative to $(objpfx), without .out.

Tested x86_64, including that the same set of files is generated in
the build directory by a build and testsuite run both before and after
the patch (except for changes to the
elf/tst-null-argv.debug.out.<number> file name), and a build with
run-built-tests=no to verify there aren't any more obvious instances
of the issue Marcus Shawcroft reported with a previous version in
<https://sourceware.org/ml/libc-alpha/2014-01/msg00462.html>.

f8c17e79fa Support expected failures in .test-result files. 
This patch, an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00195.html>, makes it
possible for .test-result files for individual tests to contain XPASS
and XFAIL rather than PASS and FAIL in cases where failure is
expected.  This replaces the marking of two individual tests with "-"
to cause them to be expected at makefile level to fail;
evaluate-test.sh will ensure it exits with status 0 for an expected
failure.

Tested x86_64.

	* scripts/evaluate-test.sh: Take new argument indicating whether
	failure is expected.
	* Makeconfig (evaluate-test): Pass argument to evaluate-test.sh
	indicating whether failure is expected.
	* conform/Makefile (test-xfail-run-conformtest): New variable.

	level.

a5f891ac8d Consistently include Makeconfig after defining subdir. 
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I
noted it was necessary to add includes of Makeconfig early in various
subdirectory makefiles for the tests-special variable settings added
by that patch to be conditional on configuration information.  No-one
commented on the general question there of whether Makeconfig should
always be included immediately after the definition of subdir.

This patch implements that early inclusion of Makeconfig in each
directory (which is a lot easier than consistent placement of includes
of Rules).  Includes are added if needed, or moved up if already
present.  Subdirectory "all:" targets are removed, since Makeconfig
provides one.

There is potential for further cleanups I haven't done.  Rules and
Makerules have code such as

ifneq   "$(findstring env,$(origin headers))" ""
headers :=
endif

to override to empty any value of various variables that came from the
environment.  I think there is a case for Makeconfig setting all the
subdirectory variables (other than subdir) to empty to ensure no
outside value is going to take effect if a subdirectory fails to
define a variable.  (A list of such variables, possibly out of date
and incomplete, is in manual/maint.texi.)  Rules and Makerules would
give errors if Makeconfig hadn't already been included, instead of
including it themselves.  The special code to override values coming
from the environment would then be obsolete and could be removed.

Tested x86_64, including that installed binaries are identical before
and after the patch.

f0881698bf Generate .test-result files for tests with special rules. 
This patch, an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00194.html> now
proposed for inclusion in glibc, extends the generation of PASS and
FAIL status in .test-result files for individual tests to cover tests
with their own custom makefile rules.  This is just adding
$(evaluate-test) calls to all such rules, since tests with multiple
commands were previously split into separate tests.

Note that the tests the makefiles expect to fail (posix/annexc and
conformtest) currently get FAIL listed in the .test-result file,
rather than XFAIL; a subsequent patch will introduce a better XFAIL
mechanism.
