I think it should be enough to provide a partial configuration only
which overrides the CONFIG defines from the generic kernel.
Have a look at the sparc* kernel (referenced from config/sparc64/defines) for example:

This should be "m68k-virt".

And this "m68k-virt_description".
Without the additional "m68k-" prefix, the resulting kernel package would be
called "linux-image-virt" which would be not unambiguous enough.

Same here, "m68k-virt".

I think we might not need this separate folder for d-i if we use the "kernelarch" approach
that arm, mips, powerpc and sparc uses. See the "kernelarch-$ARCH" folders.
