The pieces for building in cbuild and parsing with the

I have documented my work on this page, but not analyzed the results yet.

Hi Michael,
A new bug triaging question.

This one is special too because the failure is on powerpc.
This means, I cannot reproduce it easily, and scan through the toolchains
(without building).
