Remove configure tests for -mno-vzeroupper support.
GCC added support for -mno-vzeroupper in version 4.6. 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_novzeroupper): Remove configure test. * sysdeps/i386/configure: Regenerated. * sysdeps/x86_64/configure.ac (libc_cv_cc_novzeroupper): Remove configure test. * sysdeps/x86_64/configure: Regenerated. * sysdeps/x86_64/Makefile [$(config-cflags-novzeroupper) = yes]: Make code unconditional.
