If we have the LLVM port installed, CMake might pick up some of the tools installed as part of it (`llvm-ar`, `llvm-strip`, etc.) instead of the ones belonging to the host toolchain. These, of course, can't be run on the host platform, so builds would eventually fail. This made it impossible to rebuild the LLVM toolchain. We now set these variables explicitly when compiling the LLVM runtime libraries in order to avoid this issue.
