Improve `xcrun` error handling The compiler invokes `xcrun` on macOS when linking Apple targets, to find the Xcode SDK which contain all the necessary linker stubs. The error messages that `xcrun` outputs aren't always that great though, so this PR tries to improve that by providing extra context when an error occurs. Fixes https://github.com/rust-lang/rust/issues/56829. Fixes https://github.com/rust-lang/rust/issues/84534. Part of https://github.com/rust-lang/rust/issues/129432. See also the alternative https://github.com/rust-lang/rust/pull/131433.
