So what happens in this case.

Pretend shared library A references $$div from the millicode routines.  Also
assume that the main program does not reference $$div.  Also assume that
the shared library is _not_ referenced on the link line for the main
program, but instead is sucked in via dl_open calls.

The shared library will have an undefined reference for $$div which can't
be satisfied and will terminate the application if we execute a path in
the shared library which calls $$div.
