Thanks!  Unfortunately the staging branch was recently 'frozen':

  https://lists.gnu.org/archive/html/guix-devel/2020-05/msg00373.html

I was about to revert the commit, but as GHC currently only builds on
i686 and x86_64 and the CI is "half way there" already, perhaps we can
let it slide:

  https://ci.guix.gnu.org/eval/13961?status=failed

We should have a better way to poll branch status other than "read all
messages on guix-devel" or "ask Marius on IRC".
