Remove configure tests for AVX support.
GCC added support for -mavx and -msse2avx in version 4.4. Thus the configure tests for this support are obsolete, and this patch removes them. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by this patch). * sysdeps/i386/configure.ac (libc_cv_cc_avx): Remove configure test. (libc_cv_cc_sse2avx): Likewise. * sysdeps/i386/configure: Regenerated. * sysdeps/i386/i686/multiarch/Makefile [$(subdir)$(config-cflags-avx) = mathyes]: Change conditional to [$(subdir) = math]. * sysdeps/i386/i686/multiarch/s_fma-fma.c [HAVE_AVX_SUPPORT]: Make code unconditional. * sysdeps/i386/i686/multiarch/s_fma.c [HAVE_AVX_SUPPORT]: Likewise. * sysdeps/i386/i686/multiarch/s_fmaf-fma.c [HAVE_AVX_SUPPORT]: Likewise. * sysdeps/i386/i686/multiarch/s_fmaf.c [HAVE_AVX_SUPPORT]: Likewise. * sysdeps/x86_64/configure.ac (libc_cv_cc_avx): Remove configure test. (libc_cv_cc_sse2avx): Likewise. * sysdeps/x86_64/configure: Regenerated. * sysdeps/x86_64/Makefile [$(config-cflags-avx) = yes]: Make code unconditional. * sysdeps/x86_64/dl-trampoline.h (_dl_runtime_profile) [HAVE_AVX_SUPPORT || HAVE_AVX512_ASM_SUPPORT]: Make code unconditional. (_dl_runtime_profile) [!(HAVE_AVX_SUPPORT || HAVE_AVX512_ASM_SUPPORT)]: Remove conditional code. * sysdeps/x86_64/fpu/multiarch/Makefile [$(config-cflags-sse2avx) = yes]: Make code unconditional. * sysdeps/x86_64/fpu/multiarch/e_atan2.c [HAVE_FMA4_SUPPORT || HAVE_AVX_SUPPORT]: Likewise. * sysdeps/x86_64/fpu/multiarch/e_exp.c [HAVE_FMA4_SUPPORT || HAVE_AVX_SUPPORT]: Likewise. * sysdeps/x86_64/fpu/multiarch/e_log.c [HAVE_FMA4_SUPPORT || HAVE_AVX_SUPPORT]: Likewise. * sysdeps/x86_64/fpu/multiarch/s_atan.c [HAVE_FMA4_SUPPORT || HAVE_AVX_SUPPORT]: Likewise. * sysdeps/x86_64/fpu/multiarch/s_fma.c [HAVE_AVX_SUPPORT]: Likewise. * sysdeps/x86_64/fpu/multiarch/s_fmaf.c [HAVE_AVX_SUPPORT]: Likewise. * sysdeps/x86_64/fpu/multiarch/s_sin.c [HAVE_FMA4_SUPPORT || HAVE_AVX_SUPPORT]: Likewise. * sysdeps/x86_64/fpu/multiarch/s_tan.c [HAVE_FMA4_SUPPORT || HAVE_AVX_SUPPORT]: Likewise. * sysdeps/x86_64/multiarch/strcmp.S [HAVE_AVX_SUPPORT]: Likewise. * config.h.in (HAVE_AVX_SUPPORT): Remove #undef. (HAVE_SSE2AVX_SUPPORT): Likewise.
