We don't support this syscall and musl already has a fall back based on `poll`/`ppoll`. Note that the return value for `pause()` now changes to zero (from ENOSYS), because it is now based in `poll` internally and currently our `__syscall_poll` implementation returns zero when it would otherwise need to block. I have another change out the potentially change that (#27049) but we can consider that separately to this change. See #27036 and #27038
