Subject: 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]:

From b7848899a591a9de23db6afeb9992668ef8aff88 Mon Sep 17 00:00:00 2001
From: Joseph Myers <joseph@codesourcery.com>
Date: Fri, 9 Oct 2015 16:02:54 +0000
Subject: Remove configure tests for FMA4 support.

GCC added support for -mfma4 in version 4.5.  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_fma4): Remove configure
	test.
	* sysdeps/i386/configure: Regenerated.
	* sysdeps/x86_64/configure.ac (libc_cv_cc_fma4): Remove configure
	test.
	* sysdeps/x86_64/configure: Regenerated.
	* sysdeps/x86_64/fpu/multiarch/Makefile [$(have-mfma4) = yes]:
	Make code unconditional.
	* sysdeps/x86_64/fpu/multiarch/e_asin.c [HAVE_FMA4_SUPPORT]:
	Likewise.
	* sysdeps/x86_64/fpu/multiarch/e_atan2.c [HAVE_FMA4_SUPPORT]:
	Likewise.
	[!HAVE_FMA4_SUPPORT]: Remove conditional code.
	* sysdeps/x86_64/fpu/multiarch/e_exp.c [HAVE_FMA4_SUPPORT]: Make
	code unconditional.
	[!HAVE_FMA4_SUPPORT]: Remove conditional code.
	* sysdeps/x86_64/fpu/multiarch/e_log.c [HAVE_FMA4_SUPPORT]: Make
	code unconditional.
	[!HAVE_FMA4_SUPPORT]: Remove conditional code.
	* sysdeps/x86_64/fpu/multiarch/e_pow.c [HAVE_FMA4_SUPPORT]: Make
