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.
