libffi-3.4 has no API changes but has a trampoline change that is known to expose bugs in apps:
- ghc has too optimistic assumption about executable memory: https://gitlab.haskell.org/ghc/ghc/-/issues/20051
- gobject-introspection uses incorrect object as a closure: https://gitlab.gnome.org/GNOME/gobject-introspection/-/merge_requests/283

Feel free to test this flag, but be aware of possible
breakage. Let us know of any bugs!
