Initial Package Version: 2.17
Origin: Jakub Jelinek, http://sourceware.org/ml/binutils/2004-08/msg00030.html
Upstream Status: unknown
Description: Fixes ld visibility errors on ppc64, rediffed to apply with -p1.  The original was for a much earlier version of binutils, but still applies.  I couldn't find why this wasn't committed, but at the time it only fixed some of the failures he was seeing.
