I think you created a little hen and egg problem here by incorporating both
the switch to the Hadrian build system as well as the 32-bit unregisterised
and sparc64 build fixes into the same upload.

Might a good idea to upload the two build fixes unstable first to get a working
9.4.x compiler for all targets so we're able to build haskell-hadrian first.
