FIX: Kernel Compile Testcase

I screwed up the kernel compile test case by trying to improve it's logging behaviour. -.-
This fixes it.

**Sidenote:** Apart from an (intermittent *1) migration test failure and the screwed up kernel test case everything runs fine now on all 7 tested platforms. 

1) The migration test case is a race condition by design... in this one case we lost the race. It worked on this platform before, though.
