Bug#928882: unblock: [pre-approval] ghc/8.4.4+dfsg1-3

Dear Paul,

Indeed I confirm that "happy" provided by Debian buster/sid does not work on my hardware (armv5tel Kirkwood Feroceon). Just tested now after removing Ilias' deb package and reinstalling the previous one:

drakestail:/opt/bug_ghc_armel# apt remove happy

The following packages will be REMOVED:

Can you confirm that it *didn't* work with the version in sid/buster on
your system?
