 Yeah I’d seen them mapped in LegacySupport already but that’s honestly
 overkill as the checks are only in that one file.

 I’ve only noticed this one mostly due to regression testing on 10.9 (what
 fun)

 From llvm-11 and later undefined targets are an error causing build
 failures, so I guess you could simply blame the upstream due to using
 newer references and no fallback but also the compiler for only now
 complaining about this.
