On the packager's side, the lack of a mass-rebuild has rendered working
with rawhide and bugfixing f22-bugs a lottery.

My condolences - The decision to support the arm was not mine ;)

Still no tool to launch an ordered build available?

Right now, the current situation is: Random packager is rebuilding
random package with random results and weird FTBFSes, resulting in a
mixture of mixed ABI compiled packages inside of the repo.
A mass rebuild would at least minimize one source of problems. Wasn't it
you who told us, to have performed a GCC-5 mass rebuild with only a few
issues? If so, why would doing the same in rawhide not be feasible?
