        PR 17982
        * varasm.c (pending_assemble_externals): New static.
        (assemble_external_real): Meat of assemble_external split out

Can you confirm that?

Yes, it introduced the problem.

The problem with this change is that assemble_external is
called in rtx_for_function_call after cgraph_optimize calls
process_pending_assemble_externals.  These additions to the
list are never output in unit-at-a-time mode.

Steve,

Until this problem is looked at, I am using the enclosed work around.
Of course, this breaks the ia64 PR fix.
