I have GNU ld in my path, and gcc configured with just
--prefix=/folk/mrs/packages/gcc-20001129.  I have tried to confiure
with GNU ld, but that also fails, just with a different set of errors.
Conclusion, the code to prefer ccs ld over the LD in the path is
broken or incomplete.  This used to not be a problem, and needs fixing.
