I backed out this patch from my tree, and rebuilt everything
in my 10.1-RELEASE VM from the latest CURRENT sources.  At this
point, I ran into the same problem building rescue which I reported in
https://lists.freebsd.org/pipermail/freebsd-toolchain/2015-March/001545.html

I put the patch back in my tree, and recompiled everything, and the
problem went away.

To reliably build the tree, I think this patch should go in, so that these
tools are properly bootstrapped during the build.
