There is an issue in the spinlock on ARM: it's implemented with plain
non-atomic loads and stores. It seems that android ndk does not have the

We did not run the tests on emulator. Not sure what would it take to fix
the tests there. It can't be super hard, though.

Do you mean it's a compile-time issue with the path in Android.cmake?
