Subject: m68k: Use cc-cross-prefix
X-Git-Tag: firefly_0821_release~23378
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6f7127db311fe3e0ea6a2a332833f85abab6cb4b;p=firefly-linux-kernel-4.4.55.git

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.
