There is also a way in CMake to have install make these symlink for you! You can use the CMake variable `CLANG_LINKS_TO_CREATE`.
It's not clear to me (from the docs) whether you need to create the `$triple.config` file or not (which can contain other command-line arguments beyond just `-target=$triple`).
I'm happy to believe James if he says you don't need that config file though!
