Sure. I'm fine with whatever change gets us to build more packages
successfully on x32. I also appreciate these efforts, so thank
you very much!

Yeah, that mixed configuration sounds like a bad idea.

Agreed.

Agreed. Let's turn it off on architectures where it currently causes
more problems than it solves.
