The patch is wrong.  We handle the indirect part inside the compiler
before we pass it on to the assembler.

But if you can get pc-relative relocs to those plabels, it would be
the easiest thing to do.  Far better than playing with segment bases.

Perhaps you could force __text_seg to be .hidden.  I don't know if
the hpux linker supports that sort of thing though...
