No it's not true, you've misunderstood. There was a proposal to deprecate (not remove) i386 support, but it didn't happen. Even if it did happen, that wouldn't remove support for lock-free atomic ints, only i386 targets would be affected (not i486 or later), and they don't fully support lock-free atomic ints anyway.
