powerpc is the only platform where llvm isn't built with all supported targets (only the powerpc backend is enabled). So include-what-you-use can't call LLVMInitializeX86*() there. Maybe llvm should also ship the X86 backend on powerpc, as suggested by jsg@, but this is not trivial. Tests by cwen@, ok cwen@ jsg@ (maintainer)
