However, if it exists in -lgen and we don't ensure that libgen is included
(we are luckly right now because other stuff drags libgen in) or it is
a hardcoded requirement.

I'm saying the solution above is wrong because it is incomplete.  It does
not ensure we have libgen in the LIB=.

=) Just because things work.  Don't make them totally correct.
