Joseph Myers 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.

This directory contains the sources of the GNU C Library.
See the file "version.h" for what release version you have.

The GNU C Library is the standard system C library for all GNU systems,
and is an important part of what makes up a GNU system.  It provides the
system API for all programs written in C and C-compatible languages such
as C++ and Objective C; the runtime facilities of other programming
languages use the C library to access the underlying operating system.

In GNU/Linux systems, the C library works with the Linux kernel to
implement the operating system behavior seen by user applications.
In GNU/Hurd systems, it works with a microkernel and Hurd servers.

The GNU C Library implements much of the POSIX.1 functionality in the
GNU/Hurd system, using configurations i[4567]86-*-gnu.  The current
GNU/Hurd support requires out-of-tree patches that will eventually be
incorporated into an official GNU C Library release.

When working with Linux kernels, this version of the GNU C Library
requires Linux kernel version 2.6.32 or later.

Also note that the shared version of the libgcc_s library must be
installed for the pthread library to work correctly.

The GNU C Library supports these configurations for using Linux kernels:

	aarch64*-*-linux-gnu
	alpha*-*-linux-gnu
	arm-*-linux-gnueabi
	hppa-*-linux-gnu	Not currently functional without patches.
	i[4567]86-*-linux-gnu
	x86_64-*-linux-gnu	Can build either x86_64 or x32
	ia64-*-linux-gnu
	m68k-*-linux-gnu
	microblaze*-*-linux-gnu
	mips-*-linux-gnu
	mips64-*-linux-gnu
	powerpc-*-linux-gnu	Hardware or software floating point, BE only.
	powerpc64*-*-linux-gnu	Big-endian and little-endian.
	s390-*-linux-gnu
	s390x-*-linux-gnu
	sh[34]-*-linux-gnu
	sparc*-*-linux-gnu
	sparc64*-*-linux-gnu
	tilegx-*-linux-gnu
	tilepro-*-linux-gnu

If you are interested in doing a port, please contact the glibc
maintainers; see http://www.gnu.org/software/libc/ for more
information.

See the file INSTALL to find out how to configure, build, and install
the GNU C Library.  You might also consider reading the WWW pages for
the C library at http://www.gnu.org/software/libc/.

The GNU C Library is (almost) completely documented by the Texinfo manual
found in the `manual/' subdirectory.  The manual is still being updated
and contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like.  For
corrections to the manual, please file a bug in the `manual' component,
following the bug-reporting instructions below.  Please be sure to check
the manual in the current development sources to see if your problem has
already been corrected.

Please see http://www.gnu.org/software/libc/bugs.html for bug reporting
information.  We are now using the Bugzilla system to track all bug reports.
This web page gives detailed information on how to report bugs properly.

The GNU C Library is free software.  See the file COPYING.LIB for copying
conditions, and LICENSES for notices about a few contributions that require
these additional notices to be distributed.  License copyright years may be
