Perfect, just do that then, in nix guix as well (debian does, see below)

Yes, in debian testing, libffi 3.4.6-1, the flag is on by default:

Definitely not a g-golf bug. But since the flag has been introduced
precisely to deal with the yet to be fixed gobject-introspection, iiuc,
i would just continue to compile libffi passing the flag ...
