commit fa9fcc89146f08bce3b51d96d0ec9d4175db6978

    Dont fail build on unrecognized non-executable files (ticket #105)
    - Generally only executable files are critical for dependency extraction,
      whereas oddball application data files can cause unnecessary build
      failure due to libmagic misdetections etc, so just let non-executables
      pass with a warning and mark them as unknown data
    (cherry picked from commit cfcd1f9bd98d5d0fc46a84931984efec3b9d47e2)
