Subject: [PATCH] atari: allow building for ColdFire for the FireBee

While GCC is usually built with multilib to allow targetting the m5475
instead, it's simpler to just have both toolchains around and change the
host triplet prefix, and each version of the libs installed separately.

This could be done by passing ARCH=m5475 MCPU= to make.
