The commit [1] removed the Config.in.host file and moved the arm, sh,
sparc, xtensa and riscv-64 architectures dependencies. But this list
doesn't contain all elf2flt supported architectures and this breaks
the host-gcc-initial build for m68k.
Since BR2_BINFMT_FLAT is only available on no MMU case, we can rely on
BR2_USE_MMU option and remove the architecture list.
Note: SH without MMU support has been removed by [2], sparc requires
an MMU since at least [3].
