ARM has architecture name "arm" and printable name "armv2", and that
works fine:

(gdb)  set architecture arm
The target architecture is assumed to be arm
(gdb)  set architecture armv2
The target architecture is assumed to be armv2
(gdb)  set architecture arm
The target architecture is assumed to be arm

See bfd_default_scan for more.  I guess it's because the architecture
is named "m32c", but the default flag is set for m16c.  If that's so,
"set architecture m32c:m32c" should work - does it?

In that case your patch makes sense though I don't know what might break.
