  This patch remove the POWER7 ifunc wordcopy function
(_wordcopy_*_power7), since now GLIBC provides a optimized memmove/bcopy
for POWER7.

Tested on powerpc64 and powerpc64le.

	* sysdeps/powerpc/powerpc64/multiarch/Makefile [sysdep_routines]:
	Remove wordcopy-power7 object.
	* sysdeps/powerpc/powerpc64/multiarch/wordcopy-power7.c: Remove file.
	* sysdeps/powerpc/powerpc64/multiarch/wordcopy.c
	(_wordcopy_fwd_aligned): Remove POWER7 specialization.
	(_wordcopy_fwd_dest_aligned): Likewise.
	(_wordcopy_bwd_aligned): Likewise.
	(_wordcopy_bwd_dest_aligned): Likewise.
