    devel/doxygen: Fix parallel examples build (under DOCS)
    
    Tatsuki Makino wrote the original patch vs. Doxygen 1.9.1, but it no
    longer applied, so I manually re-did following his example.
    
    While here, ditch the :noninja, 1.9.6 builds fine with Ninja, too.

    Approved by:    maintainer timeout (fluffy@, 39 months)
