EDIT: I think it works now...

Motivation for this change

Tried to use this package for my printer and it took 'forever' to build (I canceled after 30+ minutes when one thing was at 7% and I gave up and used gutenprint). Had to use the arm build server to be able to try it. Thanks, @grahamc !

Things done

I built it on the arm build server from my raspberry pi 3 B and printed a test page with it. I can't figure out how to get nix-review to do anything with; it just says 'Nothing changed'.

EDIT: aarch64 is broken in newer versions. I've added it to the old old version in nixpkgs we already have, added the latest version from 18.09 which is one of, if not the last, version it worked on afaik. That's the version my pi was on and why it worked there... This time I've actually compiled all of them. >.>
