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.
