[PATCH] Fix Wundef warning for MEMCPY_OK_FOR_FWD_MEMMOVE

[Siddhesh Poyarekar <siddhesh at redhat dot com>]

Define MEMCPY_OK_FOR_FWD_MEMMOVE to 0 in x86_64 memmove.c before
including the generic string/memmove.c to get rid of this warning.

Tested to verify on x86_64 that the generated code is identical.

Siddhesh

	* sysdeps/x86_64/memmove.c: Define MEMCPY_OK_FOR_FWD_MEMMOVE
	to 0.
	* sysdeps/x86_64/multiarch/memmove.c: Likewise.
