We should adjust the build such that:

- lint is passed -errwarn=%all, just as cc is (this makes warnings be errors)
  - lint noise is enough to cause nightly to call a build "failed" 
  - lint error reporting is not "noise" based, but absolute.  You see every error every time

If we expect the build to be lint clean, we should flag every deviation from cleanliness on every build, report unclean builds as failed, and generally make it hard to ignore
