what is the remove_weak_ref issue? I want to understand this change and I can't find exact docs on this

LLDB is built against python2. If it's run in an environment where the python3 and python2 get mixed up you get an error about these functions. I think this one was mostly fixed by fixing the environment variables in the system and I'm not sure if should be handled in this way as lldb comming with Xcode may not use system python or a compatible version in the future, as it ships it's own python. (And Apple has stated that they are deprecating it in the future).

@Ukalnins I agree, but for now before this removal happens, this will do for now. I'll file a new issue regarding this.
