I don't think so.
That has nothing to do with the issue here. We're talking about the GCC Runtime Exception. It says that "You have permission to propagate a work of Target Code formed by combining the Runtime Library with Independent Modules, even if such propagation would otherwise violate the terms of GPLv3". The tarball I was talking about is precisely that "work of Target Code". But I think it could be separate files and still be one "work" as long as they're distributed together in some way.
