This needs a "depends on !MMU".
Else allmodconfig will select it, causing -m68000 to be passed to the assembler,
which may break the build depending on your version of binutils, a.o.
arch/m68k/kernel/entry.S:186: Error: invalid instruction for this
architecture; needs 68020 or higher (68020 [68k, 68ec020], 68030

Cfr. http://kisskb.ellerman.id.au/kisskb/buildresult/7416877/
BTW, it didn't break the build on my ancient workhorse binutils, but that's no
guarantee it would boot...
