s4 build farm failures

[Matthias Dieter Wallnöfer]

Particularly thanks to those wo helped to fix the build farm issues: 
Jelmer and metze I think.
But I would like to remind that the problems in the conventional 
buildsystem remain. Would be nice if someone could (or help at least to) 
find out why.

Greets,
