Subject: [PATCH] Support llvm headers in
 ${LLVM_LIBRARY_DIRS}/clang/${LLVM_VERSION_MAJOR}/

Fedora places llvm include files into that directory instead of assumed
${LLVM_LIBRARY_DIRS}/clang/${LLVM_VERSION_MAJOR}.${LLVM_VERSION_MINOR}.${LLVM_VERSION_PATCH}/include/

Try both, fail horribly when none of them exist
