Hi,

The attached patch (by Maxim Kuvyrkov) enables building GCC for Linux
when the --with-arch=cf configuration option is in effect (i.e. when
building a compiler targeting ColdFire rather than legacy m68k).

Without the patch the build fails with an error such as:

.../gcc/config/m68k/t-mlibs:45: *** Error default cpu 'mcf5475' is not
in multilib set ''.  Stop.

OK to apply?

Thanks,

Julian
