m68k: Use cc-cross-prefix

The cc-cross-prefix is new and developed on request from Geert Uytterhoeven.

With cc-cross-prefix it is now much easier to have a few default cross compile
prefixes and defaulting to none - if none of them were present.  ARCH
maintainers are expected to pick up this feature soon.
