And the fr30 port has been broken since some time after
2002-05-29.  Build succeeded then but all the tests timed out.
I haven't tried it since.  Hmm... better do that, then...

For the record: as you may imagine, the CRIS port trusts GAS
relaxation to handle varying-length branches (9-bit and 16-bit
including sign).  It's my informed opinion that this is not
worth doing in GCC (for this target) just for sake of branch
shortening since asm:s *must* in GCC be considered of inordinate
length; GCC can't do better here than GAS anyway.  (Still worth
doing for sake of switch tables; on the virtual TODO list.
Thanks to GAS broken-.word [don't puke!], offsets aren't too
long, though.)
