This indicates that the appropriate bits for long long division and
modulo arithmetic were not found. This is a fairly simple problem to
resolve.

Hmmmm... It would seem to me that the LIBGCC verbiage above should
result in having the correct library used for linkage and finding the
modules. But obviously that is not the case. In my Makefile, I have the
LIBGCC reference surrounded with {} rather than (). While I am not make
guru (quite the opposite, actually), I believe the {}s imply that an
evaluation is necessary whereas the () imply simple substitution.
I would try changing the $(LIBGCC) line above to read ${LIBGCC}
