Supporting multiple platforms matters a lot to keep everything (not
just defconfigs)
under control.
Technically, on m68k we only need two defconfigs: sun3_defconfig (Sun 3 doesn't
use a Motorola MMU) and multi_defconfig (which is the logical OR of
all the other
defconfigs, and which should work on all non-Sun 3).
The reason we have the others is to ease building of platform-specific
kernels that
need less memory. I guess most of them can be (almost) regenerated from
multi_defconfig just by disabling support for the other platforms.

So you could easily have one big common defconfig...
