 Replying to [comment:12 Ionic]:
 > The buildbot infrastructure did produce `+universal` builds for Darwin
 15, 16 and 17 and I don't understand how that would have worked in the
 first place.

 I haven't attempted to figure it out.

 with the universal variant you would want to verify that
 `configure.build_arch` is x86_64.

 comment?

 It did see the patch. I did not see the part where you were checking
 `build_arch`. Now that I see it, I note that it is only in the block of
 code that chooses whether to enable the variant by default. It is not in
 the variant itself. It would still be possible for a user on 32-bit 10.6
 to select the variant manually, which will result in a build failure.
