Ugh, that's unfortunate. I see two options:

1. We revert the patch here, or
2. You carry a local patch until you don't support 10.11 anymore

The underlying question I'm really curious to hear the answer to is why don't you use the system `libc++.dylib`? How do you make sure that you don't have ODR issues when linking against macOS system frameworks that might be linking against `libc++.dylib`?
