Ok, folded in the change blow, using one less line. I couldn't figure
out whether
it should just be part of the CONFIG_M68000 instead, which doesn't appear
to have any machine support by itself. The dragonball CPU configuration
looks really odd, because you have to build exactly one of M68{,EZ,VZ}328
into the kernel to get a successful compilation, while Kconfig allows
many other combinations.
