Turns out LLVM_LIBDIR_SUFFIX is used in several situations: (a) for the library install dir or (b) for the location where build artifact as stored in CMAKE_BINARY_DIR. (a) could accept a path but not (b), unless we derive it from (a) but I can see a lot of complication there for the testing step. Would that be ok to choke on CMAKE_INSTALL_LIBDIR being a path and not a directory component?
