You are probably exceeding the 64K jump limit, to the start of the
romcc code.  I trigger a very weird ld case when that happens so the
code will not compile.  It was the best I could do.

If you want to look at what it would take to arbitrarily relax that limit
be my guest.  If I could get a linker section to allocate space backwards
this would be trivial to fix, as it is...
