My experience with those ugly macros is that people have a flinch when
trying to remember how they work and just ignore the issue instead,
leaving it for those that have to compile for 32.  I'll switch it,
though.

Hopefully i-g-t will get cross-compiling CI and merge requests at some
point so that these bugs can just never land in the first place.
