    gtktextattributes: Use an anonymous union instead of arch-testing #ifdef
    
    This avoids having Gtk-3.0.gir differ on 32 vs 64 bit, which causes
    issues for "multilib" in Fedora/OpenSUSE type systems.
    
    See https://bugzilla.gnome.org/show_bug.cgi?id=711153 for more
    information.
