a`  Ensure that the list of libraries is valid.

        `library` is presumably provided as a command option 'libraries'.
        This method checks that it is a list of 2-tuples, where the tuples
        are (library_name, build_info_dict).

        Raise DistutilsSetupError if the structure is invalid anywhere;
        just returns otherwise.
