    Fix 'make install' when --enable-docs is used
    
    Commit
    89b918dfbb11f8ccc3162eb84097c39baccac9cc added documentation, using
    folks module as reference. It failed when doing 'make install'
    (so also 'make distcheck') because it tried to install a img/png
    directory that exists at folks but not on caribou.
