 (Just commenting on that part of the report)

 This is a problem that was pretty common, especially before libraries
 were converted to multiarch because many build systems such as libtool
 would add -L/usr/lib early in the search path. It's nice if we can fix
 these build systems, but there's a simpler workaround in having
 binutils configured to support both the host and the build
 architectures. Actually, I thought this was explicitly the case in our
 cross-toolchains for a long time, but I guess that's a recent
 regression? Seems like an Ubuntu binutils bug to me.

 Now in your case the /usr/lib/x86_64-linux-gnu/ library search path
 seems to come from spec files, which is weird: I don't think
 arm-linux-gnueabi-gcc should have a x86_86 library directory in its
 library search path, that seems like an Ubuntu gcc-4.x bug.
