    Warn but don't fail the build on missing excluded files (RhBug:745629)
    
    - If a file/directory is not to be packaged, there's not a whole lot
      point making the build fail if its missing. In case exclude is
      used to leave certain files to sub-packages, the sub-package file
      lists will catch out missing files that are really missing as a
      result of actual build failure or such (except perhaps for some
      glob cases but missing files can go unnoticed in those cases anyway)
    - backported from commit 084a00bf51a941ec85c094a436bda401fccf7d3a
