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.

	unconditional.

	[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
