I'm thinking of getting rid of the board specific defconfigs for PowerPC
4xx actually.  We already have ppc44x_defconfig that builds most boards,
and ppc40x_defconfig will be coming soon.

Of course, that might not be possible for other architectures to do.

IIRC, Fedora builds their kernels using such a mechanism, though it's
done in the RPM specfile with a perl script.  Maybe that's something to
look at to start with.
