Yes, this is the problem.  I tried the "#define SUPPORTS_WEAK 0"
recommended elsewhere and that didn't do the trick.  Thanks, Thomas.

This should be changed in the port.   The problem is subtle enough
that if you go with a ".weak" supporting assembler but not loader
you can compile lots of stuff before hitting the problem.
