Sorry for this stupid question but I'm not very familiar with use-cases for
libatomic-ops so would like to get some more clarification on what's needed here.

I know that GCC has quite a few built-ins for atomic ops and we do implement them.
I'm adding our GCC maintainer (Claudiu) in the Cc so he may jump in if needed.
