I managed to figure this out, bootstrapped 7.8 then 7.6, sent a patch
upstream (https://ghc.haskell.org/trac/ghc/ticket/8965), uploaded the
patch to Debian, and synced it into Ubuntu.  The Haskell stack is now
building on ppc64el.  GHCi is probably feasible on ppc64el next cycle,
but it will take some porting work that I *really* don't have time for
right now.

Hopefully this is the last of the bootstrapping for a while!

Cheers,
