    build: Only use G*_DISABLE_DEPRECATED flags with GTK2
    
    For now, the code has only been updated to not use any deprecated
    GTK+-2 API to ease porting to GTK+-3; API that has only been
    deprecated in GTK+-3 is still in use, so don't use those flags
    when building with --with-gtk3.
