The -L option tells Clang where it should look for libraries, but
there's no corresponding option telling it which libraries to link
against. You need to link against specific LLVM libraries like

You could do it manually ("-lLLVMCore" might work, depending on
exactly what you use), but using llvm-config as suggested on the
tutorial page is likely to be a lot simpler (and also get you any
other options that are necessary; I think LLVM expects some macros
that come out of "llvm-config --cxxflags" for example).
