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
https://github.com/b1-systems/buildbot/blob/master/qemu-master.cfg
but I noticed that it still has Stefan's rather than Michael's trivial
tree URL.

Looking at
http://buildbot.b1-systems.de/qemu/one_line_per_build
I see that most builders fail due to configure - which I guess points at
lack of compatible libfdt or dtc submodule.

Regards,
Andreas
