We can manually bootstrap packages - that's not a problem.  However, GHC
hasn't yet been ported to arm64 upstream:

  https://ghc.haskell.org/trac/ghc/ticket/7942

ppc64el may be easier as GHC does have a port for ppc64, so it's
hopefully just a small tweak to handle the endian switch.  I'll worry
about that when the port has been alive for slightly longer than a
couple of days in Launchpad!

Cheers,
