The following patch adds the multiarch definitions for m68k-linux-gnu. Tested
using a Debian/Ubuntu package build. Ok for the trunk?

Here, I'm unsure if the definition needs to be further constrained.

Classix m68k and ColdFire need different multiarch names; you need to 
avoid using a name for one on a compiler configured for the other.  (I 
think any configuration will always be --with-arch=m68k or --with-arch=cf 
so you should only need to consider M68K_ARCH rather than having 
per-multilib settings.)
