Check if basic clang compiling environment is ready. Doesn't like 'llvm-config --libs' which can returns llvm libraries in right order and duplicates some libraries if necessary, there's no correspondence for clang libraries (-lclangxxx). to avoid extra complexity and to avoid new clang breaking libraries ordering, use --start-group and --end-group. In this test case, manually identify required clang libs and hope it to be stable. Putting all clang libraries here is possible (use make's wildcard), but then feature checking becomes very slow.
