I can confirm this problem. This patch breaks builds using binutils
2.16.1. It definitely looks like a binutils bug. It builds fine with
2.17.

There are still a lot of embedded developers using 2.16.1 binutils in
their toolchains so I think that this needs to be worked around.
Otherwise we'll see lots of complaints when this gets merged into
mainline. However, I haven't figured out a workaround yet. Looking
at the binutils sourcecode doesn't reveal anything obvious, but it's
too late for my brain to work properly. Anyone else have any ideas?
