It's not a requirement, though I'm having trouble figuring out where `__gnu_unwind_frame` comes from at all. It doesn't seem to be a public function. I guess we were just assuming it's provided before, even though it's an implementation detail? If that's the case we definitely have to add a comment about that on a declaration inside libc++abi, and maybe try to get other unwind libraries to make it part of the public interface.
