Ironically autopkgtest fails¹ it's own testcases since dpkg 1.18.15 hit the
Debian archive². This is due to the following change:
 - Validate architecture arguments in Dpkg::Deps deps_parse().

This causes the architecture "megacpu" which is used in the test cases of
adt-run and autopkgtest to be invalidated.

The fix is trivial:
sed s/megacpu/powerpc/ tests/adt-run
sed s/megacpu/powerpc/ tests/autopkgtest

Any other valid arch will do, I choose powerpc because in Debian we aren't
using that on ci.d.n and probably won't ever as it is not going to be part of
jessie.
