I don't think it might be obvious. I am dubious in my own style.

I confirmed on PS3 ppc-redhat-linux.

Since the macro PPC is not used in include/llvm, I don't oppose to add
-UPPC to build llvm.
...Then, should we detect whether PPC is defined not in build configuration?
The issue could be resolved if include/llvm/Config/config.h (not
llvm-config.h) had #undef PPC.
