PATCH: lump three non-BP mem functions into libc_b

[Greg McGary]

No build regressions.

Gcc internally generates calls to non-BP memcpy and memset, so
we must have them for BP programs.  Non-BP memchr is used
by CHECK_STRING to check that '\0' occurs before the high bound.

OK?

2000-07-15  Greg McGary  <greg@mcgary.org>

	* Makerules (o-objects): Supplement with $(o-objects$o).
	* string/Makefile (o-objects.ob): Add variable to pull
	unbounded versions of memcpy, memset and memchr into libc_b.
