m68knommu: disable MC68000 cpu target when MMU is selected
As pointed out by Geert, MC68000 target needs to be disabled when
MMU support is enabled.
From Geert:
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.
