The shim only works if you invoke `/usr/bin/clang`, and that shim is for building host OS. I am not sure it is a desirable behavior for clang to call into `xcrun` because it can be very slow on first invocation and you will get error if you don't have Xcode or Commandlinetools installed (on a basic macOS install basically). I wonder if the better solution is print a very actionable diagnostics when building c++ but standard c++ library cannot be found.
