Fix Wundef warning for SEPARATE_KEY

The SEPARATE_KEY macro is never defined in any condition or
architecture.  It is effectively dead code, so remove it.
Fix Wundef warning for ELF_MACHINE_NO_RELA

This patch defines ELF_MACHINE_NO_RELA on all architectures.  Tested
only on x86_64 to verify that the sources before and after are
identical except for two instructions that pass the current line
number in dl-machine.h to assert_fail.
Fix Wundef warning for WIDE_CHAR_VERSION

fnmatch.c defines WIDE_CHAR_VERSION as 1 for wide chars, but does not
define it for the non-wide char bits.  Define it and also undef it in
fnmatch_loop.c like all other macros.
Remove configure tests for assembler CFI support.

This patch removes configure tests for assembler CFI support (and
thereby eliminates an architecture-specific case in the main
configure.ac), instead assuming that support is present
unconditionally.

The main test was added in 2003 around the time CFI support was added
to the assembler.  cfi_personality and cfi_lsda support were added to
the assembler in 2006.  cfi_sections support was added in 2009, a few
weeks before binutils 2.20 was released; it's in 2.20, the minimum
supported version, so even that configure test is obsolete.

Tested x86_64 that the installed shared libraries are unchanged by
this patch.

	* configure.ac (libc_cv_asm_cfi_directives): Remove configure
	test.
	* configure: Regenerated.
	* config.h.in (HAVE_ASM_CFI_DIRECTIVES): Remove macro undefine.
	* sysdeps/arm/configure.ac (libc_cv_asm_cfi_directive_sections):
	Remove configure test.
	* sysdeps/arm/configure: Regenerated.
	* sysdeps/nptl/configure.ac: Do not check
	libc_cv_asm_cfi_directives.
	* sysdeps/nptl/configure: Regenerated.
	* sysdeps/x86_64/nptl/configure.ac: Remove file.
	* sysdeps/x86_64/nptl/configure: Remove generated file.
	* b/sysdeps/generic/sysdep.h [HAVE_ASM_CFI_DIRECTIVES]: Make code
	unconditional.
	[!HAVE_ASM_CFI_DIRECTIVES]: Remove conditional code.
Remove powerpc special cases in configure.ac.

This patch removes two powerpc special cases in the main configure.ac.
The test for rs6000 is irrelevant to currently supported
configurations (config.guess reports rs6000 for some OSes, of which
the only one currently supported by GCC is AIX, but not for Linux).
There's no need either for a special case for powerpc*-*soft;
--without-fp suffices, and GCC doesn't have any special handling of
such a triplet.

Not tested.

	* configure.ac: Do not test for machine being rs6000.  Do not test
	for powerpc*-*soft.
	* configure: Regenerated.
Remove inline keyword from leapyear function

This syncs up the code with gnulib.
Remove unnecessary include in memmove_chk

This also has the side-effect of fixing a couple of Wundef warnings
raised from pagecopy.h.  The generated code is identical before and
after this patch.
Correctly attribute the mktime.c change to Paul Eggert

I mentioned it on the list, but forgot to put that in the changelog.
Update miscellaneous files from upstream sources.

This patch updates miscellaneous files from their upstream sources:
texinfo.tex from Texinfo, config.guess and config.sub from config.git,
install-sh from automake and move-if-change from gnulib.

Tested x86_64 that installed shared libraries are unchanged by the
patch; also looked at the generated libc.pdf manual.

	* manual/texinfo.tex: Update to version 2014-05-05.10 with
	trailing whitespace removed.
	* scripts/config.guess: Update to version 2014-03-23.
	* scripts/config.sub: Update to version 2014-05-01
	* scripts/install-sh: Update to version 2013-12-25.23.
	* scripts/move-if-change: Update from gnulib.
Add missing #include in spawn_faction_addopen.c
Add missing #include <fpu_control.h> to ARM fesetenv/feupdateenv.
Get rid of nptl/sysdeps/ entirely!
Clean up NPTL fork to be compat-only.
NPTL is no longer an add-on!
