Remove configure tests for SSE4 support.
GCC added support for -msse4 in version 4.3. Thus the configure tests for it 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_sse4): Remove configure test. * sysdeps/i386/configure: Regenerated. * sysdeps/i386/i686/multiarch/Makefile [$(config-cflags-sse4) = yes]: Make code unconditional. * sysdeps/i386/i686/multiarch/strcspn.S [HAVE_SSE4_SUPPORT]: Likewise. * sysdeps/i386/i686/multiarch/strspn.S [HAVE_SSE4_SUPPORT]: Likewise. * sysdeps/x86_64/configure.ac (libc_cv_cc_sse4): Remove configure test. * sysdeps/x86_64/configure: Regenerated. * sysdeps/x86_64/multiarch/Makefile [$(config-cflags-sse4) = yes]: Make code unconditional. * sysdeps/x86_64/multiarch/strcspn.S [HAVE_SSE4_SUPPORT]: Likewise. * sysdeps/x86_64/multiarch/strspn.S [HAVE_SSE4_SUPPORT]: Likewise. * config.h.in (HAVE_SSE4_SUPPORT): Remove #undef.
