Remove -mavx2 configure tests.
There are configure tests for the -mavx2 compiler option. AVX2
support was added in GCC 4.7, so these tests are now obsolete; this
patch removes them.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).
* sysdeps/i386/configure.ac (libc_cv_cc_avx2): Remove configure
test.
* sysdeps/i386/configure: Regenerated.
* sysdeps/x86_64/configure.ac (libc_cv_cc_avx2): Remove configure
test.
* sysdeps/x86_64/configure: Regenerated.
* config.h.in (HAVE_AVX2_SUPPORT): Remove #undef.
* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
memset-avx2 unconditionally instead of conditionally on
[$(config-cflags-avx2) = yes].
* sysdeps/x86_64/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list) [HAVE_AVX2_SUPPORT]: Make code
unconditional.
* sysdeps/x86_64/multiarch/memset.S [HAVE_AVX2_SUPPORT]: Likewise.
* sysdeps/x86_64/multiarch/memset_chk.S
[IS_IN (libc) && SHARED && HAVE_AVX2_SUPPORT]: Change conditional
to [IS_IN (libc) && SHARED].
