Done. See the patches (I can't really find "git send-email" on Guix for 
some odd reason). The hacks in the Exile package are quite ugly, but I 
don't know a better way, see below.

Minetest has a pretty ugly way of managing dependencies, actually it 
doesn't manage them at all. So it's either up to (sub)game developers to 
bundle everything into their games or up to users to download all the 
dependencies they want. In the future the game will download 
dependencies automatically which is even worse from our perspective. I 
could possibly try hacking the build system to do something but I'm 
unfamiliar with Guix's guts.
