They coexist in a single kernel in the sun3 port, thought it's not
really useful to try using both at the same time.  (Never tried it.)

Yes, it would be nice to be able to use the "stock" gdb so we don't
have to maintain our own remote-serial module.  Someone has already
done the work to make the netbsd kernel side talk the GNU protocol.
I forget who just now... maybe they'll speak up.
