When there's no Documentation/output directory, the script will
complain about those missing references:

        Documentation/doc-guide/sphinx.rst: Documentation/output
        Documentation/doc-guide/sphinx.rst: Documentation/output
        Documentation/process/howto.rst: Documentation/output
        Documentation/translations/it_IT/doc-guide/sphinx.rst: 
Documentation/output
        Documentation/translations/it_IT/doc-guide/sphinx.rst: 
Documentation/output
        Documentation/translations/it_IT/process/howto.rst: Documentation/output
        Documentation/translations/ja_JP/howto.rst: Documentation/output
        Documentation/translations/ko_KR/howto.rst: Documentation/output

Those are false positives, so add an ignore rule for them.
