- Subject: fix bootstrap problem on some ELF ports with DWARF
I've had some reports of a bootstrap problem on some ELF ports that
use DWARF after my last patch. I posted this patch earlier; DJ and
Paolo said it fixed the problems they saw, so I'll put it in.
Bootstrapped with C only on powerpc-darwin8.
