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.
