They are done on build.gnome.org (same machine as gnome-continuos).
However, this is just because its a beefy machine we had available.
There is no particular reason that it has to be from there. 

build.gnome.org it is also where we host the repo, so with a multi
-machine build it would need a bit more work to sync the result to a
single repo. I'm sure this is solvable though.

Cross-building the entire sdk is going to be massive pain. Especially
the gobject-introspection related parts.
