While that might technically work, such cross vs native differences are
fragile and in a lot of cases, I've had to fix them, so I strongly
prefer to not add cross vs native differences to the build unless
necessary.

Here, no part of an arch-only build needs gtk-doc. For this, it does not
matter whether the build is cross or native. It applies to any arch-only
build. In particular, disabling gtk-doc, also speeds up the build. I
actually performed an arch-only and a full build to verify that no
files go missing by this change using reproducible builds.

Is this line of reasoning convincing to you?
