I was thingk about it in the shower this morning, and _knew_ I'd be seeing
some mail from you.  You see, I really missed the whole point:  The
special PIC stubs are really only needed when intermixing calls to dynamic
libraries and statically linked PIC routines - which case we currently
ignore.  The fully statically linked case be solved by changing gcc to
reserve r19, although I think I'll leave the code there to add the stubs
and .plt entries.  With your fixes, of course!
