commit 5c65b9108d2eabee9d885dcc61df5862bd3115fe

    ruby: Only rebuild rdoc when absolutely necessary.
    
    Rebuilding the ruby documentation takes 51 seconds on my laptop, and
    that's a significant fraction of the entire build.  Make sure we only
    rebuild the documentation when necessary.
