But on the Libc++AndAbiBuilder, there's no way to set the CMake argument (or is there?):
No, there isn't. Should be simple enough to add though. I'd add it as a dict param.

They are lit test args, and triggers for -D defines for various weird configurations (e.g. single threaded). I don't think there is one for the unwinder (nor do I think it makes sense to add one for that).
