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].
