Maybe worth mentioning that the prom-env test for sparc64 has just been
enabled a couple of commits ago (6b591ad613010f13). There was an issue
with that test for the sparc64 target last year, but IIRC it only
affected 32-bit hosts and has been fixed, so I think/hope this is a
different issue now...
