Enable AVX2 optimized memset only if -mavx2 works
* config.h.in (HAVE_AVX2_SUPPORT): New #undef. * sysdeps/i386/configure.ac: Set HAVE_AVX2_SUPPORT and config-cflags-avx2. * sysdeps/x86_64/configure.ac: Likewise. * sysdeps/i386/configure: Regenerated. * sysdeps/x86_64/configure: Likewise. * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add memset-avx2 only if config-cflags-avx2 is yes. * sysdeps/x86_64/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Tests for memset_chk and memset only if HAVE_AVX2_SUPPORT is defined. * sysdeps/x86_64/multiarch/memset.S: Define multiple versions only if HAVE_AVX2_SUPPORT is defined. * sysdeps/x86_64/multiarch/memset_chk.S: Likewise.
