./x check std --target aarch64-apple-ios fails when cross-checking due to missing xcrun #133840Description
On a non-mac host, checking std for an ios target fails with the following error:
> ./x check std --target aarch64-apple-ios
Building bootstrap
Finished `dev` profile [unoptimized] target(s) in 0.8s
error occurred: Failed to find tool. Is `xcrun` installed? (see https://docs.rs/cc/latest/cc/#compile-time-requirements for help)
Build completed unsuccessfully in 0:00:01
Ideally I should be able to check any target from any host.
