This is a know bug with binutils 2.16.1. You can work around it by
either reverting commit 549e8152de8039506f69c677a4546e5427aa6ae7 or
upgrading to a newer version of binutils.

Nobody has a fix for this problem yet. (it's definitely a binutils bug,
but the kernel exposed it where it wasn't an issue before. I don't know
if support for 2.16.1 is going to be depreciated due to this. It seems
like there are still a fair few users of binutils 2.16.1)
