I think that any function that can get added after you've potentially deleted its definition needs to be handled the same way, otherwise you can end up w/ the same kind of bugs. Adding all the functions from BuildLibCalls.h seems roughly correct, since I don't recall running into anything that fails this way that isn't either on that list or in the list of RuntimeLibcalls.
