I'm OK with the revert since it's necessary. It's a bit of a step back though. Would leaving a comment that it should probably depend on Libsystem instead as soon as the libcxx situation is sorted help us remember to fix this up?

@toonn, added a comment as you suggested.

Maybe the Darwin project should be updated and issues related to stuff like this should be added?

[toonn]

I agree, adding an issue describing the problem and linking here and to the original PR and then adding it to the project board would be good. I'm not sure who has access to that board though? (The LLVM 9 update can be removed for example, we skipped 9 and went to 11.)

I opened #163052 so we have something to add to the Darwin project board. Any further information is welcome. Is this problem due to our Libsystem being as old as it is?
