How to build solarus-quest-editor on raspberry pi (RetroPie)

[schamp]

I wanted to set up a quest development environment for my kids running on our RetroPie.  The extension pack for running quests works well, but there was no build for arm, so I had to roll my own.

I eventually got it working, here's a gist with the patches I had to make to get it building, in case anyone is interested:  https://gist.github.com/schamp/18255d7ec07795624374cc457f746417

If you want to clean it up and incorporate it into the main build, go for it.
