Since this cache value overrides the defaults, we end up with `clang` linked to `clang-20`, and some `${triple}-clang*` links, but we're missing `clang++`.  This makes for a toolchain with inconsistent behavior when used in someone's `$PATH`.

We'll add the default symlinks to our list so that C and C++ programs are both built as expected when `clang` and `clang++` are invoked.
