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.
