print length in strrchr benchtest

The return criteria of strrchr() is to read till NULL even if the
search character is hit.  So its better to print len instead of pos.
Minor formatting fix
Allow sys/auxv.h to be used from the testsuite on powerpc and sparc.

elf/tst-auxv.c includes misc/sys/auxv.h, which ends up not actually
being included due to the guard overlap, and getauxval becomes an
implicit declaration and implicit pointer conversion which means, at
best, the test isn't actually testing what it thinks it is and, at
worst, it'll crash and burn on platforms where implict pointer
conversion is a Very Bad Thing.

	* sysdeps/powerpc/bits/hwcap.h: Allow _SYSDEPS_SYSDEP_H guard as a
	synonym for _SYS_AUXV_H to allow direct inclusion.
	* sysdeps/sparc/bits/hwcap.h: Likewise.
	* sysdeps/powerpc/sysdep.h: Define _SYSDEPS_SYSDEP_H instead of
	_SYS_AUXV_H so we can include sysdep.h and sys/auxv.h together.
	* sysdeps/sparc/sysdep.h: Likewise.
Add GLIBC_2.17 to librt in Version.def

This is needed because the version is used in SHLIB_COMPAT.
Update ARM ulps for VFPv4 (bug 16600).

	[BZ #16600]
	* sysdeps/arm/libm-test-ulps: Update for VFPv4.
Complete _BSD_SOURCE / _SVID_source followup cleanup.

This patch completes the headers cleanup consequent on removal of
_BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations):

* #endif conditionals that referred to BSD or SVID are updated.

* Redundant __USE_* tests in cases involving __USE_MISC are removed.
  This includes cases such as __USE_MISC || __USE_ISOC99, where
  __USE_MISC is redundant (because __USE_MISC is only ever defined in
  the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99
  is also defined; the same applies to the non-XSI-extended POSIX
  versions), and cases involving __USE_GNU, where __USE_GNU is
  redundant (because if __USE_GNU is defined, so are the other __USE_*
  macros).  There may well be other cases of __USE_FOO || __USE_BAR
  tests that could be simplified because one macro implies the other;
  this patch only addresses cases involving __USE_MISC.

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.
