[Buildroot] [PATCH] arch/Config.in: BR2_BINFMT_FLAT remove architecture dependencies

[Buildroot] [PATCH] arch/Config.in: BR2_BINFMT_FLAT remove architecture dependencies

[Romain Naour]

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 contains all elf2flt supported architecture
and break 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].

Applied to master after adding a reference to the autobuilder failure
that is fixed by this commit. Thanks!
