— Remove broken forwarding target for ObjFW-RT.
While it calls the correct method, it does not pass the correct object
to that code. This would need a trampoline that replaces the object,
written in assembly for each platform. Therefore, it will be only
available for some platforms later and the broken code will not come
back. (user: js, size: 25492) [annotate] [blame] [check-ins using]
