So your bootstrap complier is broken.

Sorry, but I'm not going to investigate this failure further unless you also experience it with a valid configuration. (I strongly suspect Jeremy won't either.)

Put xcrun and xcodebuild back, set your active developer directory to Xcode, and try building again.

No, xcrun uses the tools that are in your active developer directory.

No. As I said, invoking /usr/bin/clang invokes the compiler in your active tools directory. (I think. It could hypothetically use the compiler selected by `xcrun`, but I've never butchered `xcrun` to do the wrong thing.)
