[PATCH] newlib: powerpc: move libc machine list to Makefile

[Mike Frysinger <vapier@gentoo.org>]

This makes the makefile logic a bit cleaner so we don't have two
files maintaining lists of sources & objects.  Since the logic is
tied to cpu capabilities, past those boolean settings down from
the configure logic to the makefile logic.

This will also make it easier to throw away the configure script
in a follow up commit and just keep the makefile.
