[Qemu-devel] [PATCH] Fix linker scripts

From:	Gerd Hoffmann
Subject:	[Qemu-devel] [PATCH] Fix linker scripts
Date:	Fri, 26 Aug 2011 11:16:10 +0200
Remove PROVIDE_HIDDEN and ONLY_IF_{RO,RW} from linker scripts to make
them work with older binutils versions.  Fixes *-bsd-user build on
OpenBSD 4.9 which ships binutils 2.15.
