[PATCH 12/20] libcpu-rt-c/x86-64: Add strcmp

	* sysdeps/x86_64/Makefile (cpu-rt-c-routines): Add strcmp.
	* sysdeps/x86_64/multiarch/Makefile
	(libcpu-rt-c-sysdep_routines): Add strcmp-sse2.
	strcmp-sse2-unaligned, strcmp-ssse3, strcmp-sse4_2 and
	strcmp-avx2.
	* sysdeps/x86_64/multiarch/strcmp-avx2.S: Support libcpu-rt-c.
	* sysdeps/x86_64/multiarch/strcmp-sse2-unaligned.S: Likewise.
	* sysdeps/x86_64/multiarch/strcmp-sse2.S: Likewise.
	* sysdeps/x86_64/multiarch/strcmp-ssse3.S: Likewise.
	* sysdeps/x86_64/multiarch/strcmp.c: Likewise.
