This patch simplify the default bcopy symbol for powerpc64 by just using
memmove instead of implementing using the default bcopy. Since the
symbol is deprecated, it trades speed by code size.
Tested on powerpc64 and powerpc64le.

* sysdeps/powerpc/powerpc64/multiarch/bcopy-ppc64.c (__bcopy_ppc):
Rewrite to call __memmove_ppc instead of include default
implementation.
