[Nico Weber via Phabricator via cfe-commits]

thakis added a comment.

I just verified that that does indeed happen, and it does:

  $ strace out/gn/bin/clang --target=x86_64-apple-macos -x c -c /dev/null 2>&1 | grep xcrun
  access("/usr/bin/xcrun", F_OK)          = -1 ENOENT (No such file or directory)
