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