Fix error messages related to undefined symbols in lwlink Make lwlink not complain about seciton base and length symbols. Also silence duplicate complaints about undefined symbols. There is no need to complain about undefined symbols during the file/section resolution stage! If they are truly undefined, they'll still be undefined at the reference resolution stage.
