Use -std=gnu11 instead of -std=gnu99.
Now that GCC 4.7 or later is required to build glibc, this patch moves the build from using -std=gnu99 to -std=gnu11 (option added in 4.7). This allows use of C11 features from GCC's headers, such as new float.h macros and max_align_t. Tested for x86_64 and x86 (testsuite; installed stripped shared libraries are unchanged by the patch on x86_64, while I see some slight code reordering of no significance on x86). * Makeconfig (CFLAGS): Use -std=gnu11 instead of -std=gnu99. * Makefile ($(objpfx)c++-types-check.out): Filter out -std=gnu11 instead of -std=gnu99. * configure.ac (systemtap): Test with -std=gnu11 instead of -std=gnu99. * configure: Regenerated. * math/gen-auto-libm-tests.c: Use -std=gnu11 instead of -std=gnu99 in compilation command in comment.
