Comment (by barracuda156):

 Replying to [comment:3 harens]:
 > I'm happy to do that. Would you mind explaining a bit more why it breaks
 for Rosetta? Does it cause a build failure if the condition isn't applied
 here? Also, there are [https://github.com/macports/macports-
 ports/search?q=powerpc+%22-latomic%22&type=code at least 4 different
 ports] that apply `-latomic` based on `os.arch`. These might need to be
 changed.

 Thank you!

 I meant it likely just won't be used because `os.arch` will be x86_64, and
 then build gonna fail since ppc needs `-latomic`. I will need to test that
 specifically to say for sure (now on PPC machine and away from Intel).
