Hmmm. I'm not sure where I would put the changes, since there is no 
t-.... file for coff.

But in any case, I think I may have identified the problem: My build 
didn't quite work after all; I actually got compile failure at a certain 
point, but after enough was already there for my build script to assume 
everything was OK, and all files to be generated. Error is:

if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi

"-mc68020"? Surely that should be "-m68020"?
