These are actually Ken's patches--I told him I'd take move them from
p3 into devo.
* tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
the register name.
* tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
M68KCOFF.
