Builds use the newest GitHub code, and also build more efficiently - even if the x86-64 build fails, all of the others will still build allowing you to see if the build fail is platform specific

I have a spare pi laying around, so soon we'll either be getting another pi builder, or distcc for faster compile times. Tell me which you want.
distcc sounds interesting, if you can make it work

The pi is failing at builds after the submodule update, I know a fix and will apply it soon.
Submodules were not being updated, they are now

The PullRequest Builder is now fixed

Buildserver fixed - the pullrequest builds weren't working, now they are.
New pi is going to be going into action tonight

Are you also going to create an automated android buildserver?
I'd really like to, but I have no idea how
If somebody could make a guide it would be great.
Same for mac and windows builds. - I'd like to make them but I don't really know how.
