PATCH: memcpy doubles as mempcy, not bcopy

[Greg McGary <greg at kayak dot mcgary dot org>]

This was a pretty stupid, but had no impact non-BP code, and still
doesn't...

Here's where the file is included from:
i586/mempcpy.S:#include <sysdeps/i386/i586/memcpy.S>

OK?

2000-06-25  Greg McGary  <greg@mcgary.org>

	* sysdeps/i386/i586/memcpy.S: redefine memcpy as mempcpy,
	not as bcopy.
