Hi!
This is https://github.com/OpenMP/spec/issues/3183
There is an agreement that we should return 1 team inside of target,
even if that target is inside of host teams. We were doing that
when offloading and not during host fallback, r12-5151 should fix that
even for host fallback.
Bootstrapped/regtested on x86_64-linux and i686-linux and tested with
nvptx offloading on the former.
