Now I remember why I didn't pull this in. With your patch, I see the same
failures you are seeing in my env. with

GNU Make 4.1
Built for x86_64-pc-linux-gnu
Copyright (C) 1988-2014 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

I will have to figure out a different way to fix the problem.

thanks,
