This issue brought up an interesting question:
Why didn't the buildbots report this build breakage on ppc-next branch?

Both of us didn't see any buildbot emails for quite a while - was this
disabled for some reason?

I didn't find the answer in
but I noticed that it still has Stefan's rather than Michael's trivial
tree URL.

Looking at
I see that most builders fail due to configure - which I guess points at
lack of compatible libfdt or dtc submodule.
