@zmodem: it seems, from https://issues.chromium.org/issues/325410295, that the issue was with `strip` from Apple cctools, and seems that also happens with `ld`, while `llvm-strip` seems to work fine. Do you think it will be fine to re-revert since the problem was not with the implementation of LLD or any other tool in LLVM?
