thanks

Remaining things wrong with this transition:

* esajpip FTBFS due to <https://bugs.debian.org/795084>
  and I would be inclined to remove it from testing if it holds up the
  transition (popcon = 1).

* ldc FTBFS because LLVM static libraries need to be rebuilt with
  g++-5, related to <https://bugs.debian.org/794935>

* libffado FTBFS because libdbus-c++ needs a transition
  <https://bugs.debian.org/795065>

* lierolibre FTBFS on amd64 and i386, which seems to be caused by the new
  upstream version of libconfig not being 100% API-compatible with the old
  <https://bugs.debian.org/795437>. It has never built successfully on
  non-x86 in any case.

To be transitioned, but not in testing anyway:

* flush FTBFS due to <https://bugs.debian.org/790094>
