BUG: Make sure all source files are found before generating.

  - Previously this was done implicitly by the check for a target
    link language which checked all source full paths.
  - The recent change to support computing a link language without
    finding all the source files skipped the implicit check.
  - This change adds an explicit check to find all source files.
