Still paying the cost of not having refactored all architecture handling
in the 3.x branch so we have this broken hybrid of arch/bits which is
unreliable.
Fixes#45687.
This is really just a band-aid, our current buildsystem doesn't work well for
cross-compilation and needs a thorough refactoring to do so.
