There seems to be some indeterminacy going on here; all four powerpc*
platforms broke for 15.x, but the stable/13 and stable/14 builds (which
I think have the same llvm code) worked fine.  The weekly snapshot builds
happen on amd64 hardware, so using a powerpc host is not required.

I have the files from the failed builds, so I can give you the logs and the
preprocessed source and build script that clang reported.  That might be
enough to reproduce it?  Let me know if you'd like those.
