So, I've done what Arnd suggested, but I don't have a working
cross-compiler than can do h8300 or c6x.  Could you test the attached
patch and see if it gets things working for you?

Also, do you have a handy place to grab a cross-compiler for h8300
without having to build one?  The kernel.org ones don't seem to work for
h8300.
