I am not 100% sure whether the problem applies to the newer versions.

At least for 4.0, the failure is different:

I have checked the upstream sources and couldn't even find any definitions of
CreateHostNativeRegisterContextLinux for the PPC targets. But I also haven't
worked on the LLVM code yet, so it might be just defined elsewhere.
