As I said, the variant would be forcibly disabled if the iOS SDK is absent (as reported by `xcrun` or `xcodebuild`).

The compiler-rt build system previously used a dummy SDK; perhaps it tried to build the ARM slices erroneously. It was recently revised to require real SDKs, so the ARM bits are not selected if there's no iOS SDK.
