I think we need to figure out where that something else is.  Your
empirical evidence (on HP-UX) certainly suggests that this call is
unnecessary, but I'd like to understand what is making sure that we call
assemble_external for a reference to a global function not defined in
the current translation unit.

Once we understand that, the patch is probably OK; certainly, it would
be nice to reduce the presence of this kind of thing in the front ends.

Thanks,
