I noticed this on the absolute latest HEAD (actually, trying to build xdev
even). I was able to build it successfully with the last revision I had -
r251213 (~June 1st?) - and now I'm currently building for BeagleBone using
r251352 (June 3rd), and everything seems okay so far.

I suppose the simplest work around would be to check out one of these
revisions instead.
