Thanks for the feedback. I don't think we really need to find a
workaround, as I don't think we care much about m68k_cf support. It's
just that I prefer to have a clear relationship between an exclusion in
Buildroot (don't build this package) and a gcc or binutils bug, rather
than random architecture exclusions.

Thanks!
