arch: define dependencies for the binfmt flat formats
The situation looks like following for elf2flt and binfmt FLAT:
* Only gcc for bfin/m68k implements
-msep-data (BR2_BINFMT_FLAT_SEP_DATA) and
-mid-shared-library (BR2_BINFMT_FLAT_SHARED), so the corresponding
options are made only visible on those architectures.
* When the default of BR2_BINFMT_FLAT_ONE is used on m68k, broken
binaries are produced, which mainly end up in SIGILL, so do not use
it for m68k.

[Thomas:
- also add the dependencies on m68k/bfin to BR2_BINFMT_FLAT_SHARED
- rework commit log.]
