Cross-compiling on non-mac with --target=aarch64-apple-ios fails with (among many other things):

 1:08.42 warning: build failed, waiting for other jobs to finish...

The error comes from third_party/rust/cc/src/lib.rs, which runs xcrun to find the iPhoneOS SDK location... which might actually not even match what the build system is using on mac, so it's not only a problem on cross-compiles. Only a more direct one on cross-compiles.
