[PATCH] Call memcpy in generic mempcpy

[OndÅej BÃlka <neleai at seznam dot cz>]

As most ports have optimized memcpy implementatin but I
did not find mempcpy implementation a best way to handle it genericaly is
simply call memcpy.

OK to commit?

        * string/mempcpy.c: Implement by calling memcpy.
