[PATCH] D119850: Darwin: introduce a global override for debug prefix map entries

[Nico Weber via Phabricator via cfe-commits]

thakis added a comment.

(I wish there was a flag that said "clang, never ever read any env vars please". Some people think that builds should be deterministic and not depend on random env vars people might have set (and then not do correct incremental rebuilds when the value of such env var flags change). But given that clang already reads a whole bunch of such env vars and we can always add such a flag later, I suppose this change doesn't make things that much worse.)
