Haha, now you have OS_ARCH (shouldn't that be called HOST_ARCH?) instead,
which is available only for UM?

This does remove functionality.
It allows to build a kernel using e.g. "make ARCH=m68k".
Perhaps this can be moved to generic code? Most (not all!) cross-toolchains
are called $ARCH-{unknown-,}linux{,-gnu}.
Exceptions are e.g. am33_2.0-linux and bfin-uclinux.

Why not merge these two, so git copy/rename detection will show only the real
changes?
