Is this commented out because of a missing symbol linker error `___isPlatformVersionAtLeast`? I found that the issue here is something to do with the `builtins` library. While I was investigating I built the target `builtins` and then suddenly the linker error went away - I'll investigate the source of this build order dependency when I have time.

If we can avoid removing this test, that would be preferable
