5f245f3bfb Add crt1-2.0.o for glibc 2.0 compatibility tests
Starting from glibc 2.1, crt1.o contains _IO_stdin_used which is checked
by _IO_check_libio to provide binary compatibility for glibc 2.0.  Add
crt1-2.0.o for tests against glibc 2.0.  Define tests-2.0 for glibc 2.0
compatibility tests.  Add and update glibc 2.0 compatibility tests for
stderr, matherr and pthread_kill.

e6e3c66688 crypt: Remove libcrypt support
All the crypt related functions, cryptographic algorithms, and
make requirements are removed,  with only the exception of md5
implementation which is moved to locale folder since it is
required by localedef for integrity protection (libc's
locale-reading code does not check these, but localedef does
generate them).

Besides thec code itself, both internal documentation and the
manual is also adjusted.  This allows to remove both --enable-crypt
and --enable-nss-crypt configure options.

Checked with a build for all affected ABIs.

b121fdc552 Remove 'grp' and merge into 'nss' and 'posix'
The majority of grp routines are entry points for nss functionality.
This commit removes the 'grp' subdirectory and moves all nss-relevant
functionality and all tests to 'nss', and the 'setgroups' stub into
'posix' (alongside the 'getgroups' stub).  References to grp/ are
accordingly changed.  In addition, compat-initgroups.c, a fallback
implementation of initgroups is renamed to initgroups-fallback.c so that
the build system does not confuse it for nss_compat/compat-initgroups.c.

Build time improves very slightly; e.g. down from an average of 45.5s to
44.5s on an 8-thread mobile x86_64 CPU.

64d9580cdf Allow glibc to be built with _FORTIFY_SOURCE
Add --enable-fortify-source option.

It is now possible to enable fortification through a configure option.
The level may be given as parameter, if none is provided, the configure
script will determine what is the highest level possible that can be set
considering GCC built-ins availability and set it.
If level is explicitly set to 3, configure checks if the compiler
supports the built-in function necessary for it or raise an error if it
isn't.

If the configure option isn't explicitly enabled, it _FORTIFY_SOURCE is
forcibly undefined (and therefore disabled).

The result of the configure checks are new variables, ${fortify_source}
and ${no_fortify_source} that can be used to appropriately populate
CFLAGS.

A dedicated patch will follow to make use of this variable in Makefiles
when necessary.

Updated NEWS and INSTALL.

Adding dedicated x86_64 variant that enables the configuration.

2d7ed98add Makerules: fix MAKEFLAGS assignment for upcoming make-4.4 [BZ# 29564]
make-4.4 will add long flags to MAKEFLAGS variable:

    * WARNING: Backward-incompatibility!
      Previously only simple (one-letter) options were added to the MAKEFLAGS
      variable that was visible while parsing makefiles.  Now, all options
      are available in MAKEFLAGS.

This causes locale builds to fail when long options are used:

    $ make --shuffle
    ...
    make  -C localedata install-locales
    make: invalid shuffle mode: '1662724426r'

The change fixes it by passing eash option via whitespace and dashes.
That way option is appended to both single-word form and whitespace
separated form.

While at it fixed --silent mode detection in $(MAKEFLAGS) by filtering
out --long-options. Otherwise options like --shuffle flag enable silent
mode unintentionally. $(silent-make) variable consolidates the checks.

Resolves: BZ# 29564

900fa25736 stdio: Remove the usage of $(fno-unit-at-a-time) for errlist.c
The errlist.c is built with -fno-toplevel-reorder to avoid compiler to
reorder the compat assembly directives due an assembler issue [1]
(fixed on 2.39).

This patch removes the compiler flags by split the compat symbol
generation in two phases.  First the _sys_errlist_internal internal
without any compat symbol directive is preprocessed to generate an
assembly source code.  This generate assembly is then used as input
on a platform agnostic errlist-data.S which then creates the compat
definitions.  This prevents compiler to move any compat directive
prior the _sys_errlist_internal definition itself.

Checked on a make check run-built-tests=no on all affected ABIs.

3ee318c923 Remove -z combreloc and HAVE_Z_COMBRELOC
-z combreloc has been the default regadless of the architecture since
binutils commit f4d733664aabd7bd78c82895e030ec9779a92809 (2002). The
configure check added in commit fdde83499a (2001) has long been
unneeded.

We can therefore treat HAVE_Z_COMBRELOC as always 1 and delete dead code
paths in dl-machine.h files (many were copied from commit a711b01d34
and ee0cb67ec2).

114d07fd9a Add and use link-test-modules-rpath-link [BZ #28455]
DT_RUNPATH is only used to find the immediate dependencies of the
executable or shared object containing the DT_RUNPATH entry:

1. Define link-test-modules-rpath-link if $(build-hardcoded-path-in-tests)
is yes.
2. Use $(link-test-modules-rpath-link) in build-module-helper so that
test modules can dlopen modules with DT_RUNPATH.
3. Add a test to show why link-test-modules-rpath-link is needed.

Also, to avoid adding both LFS and 64 bit time support on internal
tests they are moved to a newer 'testsuite-internal' module.  It
should be similar to 'nonlib' regarding internal definition and
linking namespace.

This patch also enables LFS and 64 bit support of libsupport container
programs (echo-container, test-container, shell-container, and
true-container).

Checked on x86_64-linux-gnu and i686-linux-gnu.

23645707f1 Replace --enable-static-pie with --disable-default-pie
Build glibc programs and tests as PIE by default and enable static-pie
automatically if the architecture and toolchain supports it.

Also add a new configuration option --disable-default-pie to prevent
building programs as PIE.

Only the following architectures now have PIE disabled by default
because they do not work at the moment.  hppa, ia64, alpha and csky
don't work because the linker is unable to handle a pcrel relocation
generated from PIE objects.  The microblaze compiler is currently
failing with an ICE.  GNU hurd tries to enable static-pie, which does
not work and hence fails.  All these targets have default PIE disabled
at the moment and I have left it to the target maintainers to enable PIE
on their targets.

build-many-glibcs runs clean for all targets.  I also tested x86_64 on
Fedora and Ubuntu, to verify that the default build as well as
--disable-default-pie work as expected with both system toolchains.

f3eef96390 Run conform/ tests using newly built libc
Although the conform/ header tests are built using the headers of the
glibc under test, the execution tests from conformtest (a few tests of
the values of macros evaluating to string constants) are linked and
run with system libc, not the newly built libc.

Apart from preventing testing in cross environments, this can be a
problem even for native testing.  Specifically, it can be useful to do
native testing when building with a cross compiler that links with a
libc that is not the system libc; for example, on x86_64, you can test
all three ABIs that way if the kernel support is present, even if the
host OS lacks 32-bit or x32 libraries or they are older than the
libraries in the sysroot used by the compiler used to build glibc.
This works for almost all tests, but not for these conformtest tests.

Arrange for conformtest to link and run test programs similarly to
other tests, with consequent refactoring of various variables in
Makeconfig to allow passing relevant parts of the link-time command
lines down to conformtest.  In general, the parts of the link command
involving $@ or $^ are separated out from the parts that should be
passed to conformtest (the variables passed to conformtest still
involve various variables whose names involve $(@F), but those
variables simply won't be defined for the conformtest makefile rules
and I think their presence there is harmless).

This is also most of the support that would be needed to allow running
those tests of string constants for cross testing when test-wrapper is
defined.  That will also need changes to where conformtest.py puts the
test executables, so it puts them in the main object directory
(expected to be shared with a test system in cross testing) rather
than /tmp (not expected to be shared) as at present.

Tested for x86_64.

For Hurd (which remains !PTHREAD_IN_LIBC), a few #define redirects

088d3291ef y2038: Add test coverage
It is enabled through a new rule, tests-y2038, which is built only
when the ABI supports the comapt 64-bit time_t (defined by the
header time64-compat.h, which also enables the creation of the
symbol Version for Linux).  It means the tests are not built
for ABI which already provide default 64-bit time_t.

The new rule already adds the required LFS and 64-bit time_t
compiler flags.

354e4c1add test-container: Install with $(sorted-subdirs) [BZ #24794]
Commit 35e038c1d2 started to use an
incomplete list of subdirs based on $(all-subdirs) causing
testroot.pristine to miss files from nss.

Tested if the list of files in testroot.pristine remains the same.

	[BZ #24794]
	* Makeconfig (all-subdirs): Improved source comments.
	* Makefile (testroot.pristine/install.stamp): Pass
	subdirs='$(sorted-subdirs)' to make install.

a8ff215e56 Makeconfig: Move -Wl,-rpath-link options before library references
Previously, the -Wl,-rpath-link options came after the libraries
injected using LDLIBS-* variables on the link editor command line for
main programs.  As a result, it could happen that installed libraries
that reference glibc libraries used the installed glibc from the system
directories, instead of the glibc from the build tree.  This can lead to
link failures if the wrong version of libpthread.so.0 is used, for
instance, due to differences in the internal GLIBC_PRIVATE interfaces,
as seen with memusagestat and -lgd after commit
f9b645b4b0 ("memusagestat: use local glibc
when linking [BZ #18465]").

The isolation is necessarily imperfect because these installed
libraries are linked against the installed glibc in the system
directories.  However, in most cases, the built glibc will be newer
than the installed glibc, and this link is permitted because of the
ABI backwards compatibility glibc provides.

e30fb31c0a Makeconfig: Move $(CC) to +link command variables
This change is needed to add linker flags which come very early in the
command linke (before LDFLAGS) and are not applied to test programs
(only to installed programs).

94a4e9e4f4 Extend BIND_NOW to installed programs with --enable-bind-now
Commit 2d6ab5df3b ("Document and fix
--enable-bind-now [BZ #21015]") extended BIND_NOW to all installed
shared objects.  This change also covers installed programs.
