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.
