There are instances of these two failures for all qemu-upstream-4.[456]-
testing branches on list this morning.

I can't see any for qemu-upstream-unstable.

The 4.2 and 4.3 testing branches are blocked by an unrelated build failure
(related to upgrading the build hosts to Jessie, I think). I wouldn't be at
all surprised if they also suffered from this issue once that is fixed.
