Alright, making some progress here. (see: http://i.imgur.com/DXkJ5CH.jpg)
The Sys directory has to be manually copied to the Binaries directory and the global installation won't work anymore but this is usable for Lutris.
I'll commit my changes to https://github.com/lutris/dolphin then we can discuss on how we can merge all of this into master.
Edit: Changes I made are located here https://github.com/lutris/dolphin/commit/fe16f3950f197085432743e07b270dbd8ac98ddf
