I have been hacking on getting ld.old to cross-link for all architectures. 
I discovered no one has ever tried this for ns32k. :-)

Below are the changes I had to make to get it to work. Do they seem
reasonable (I don't have hardware to test, I just made sure the new ld
linked, and that the relocations looked right)?

Take care,

Bill
