    build: add option --disable-user-help to speed the build
    
    It's a hack, as the comment explains... I'm not sure the non-recursive
    make was a good idea.... Hacking on a plugin was really painful, since
    the 'make install' is necessary, but it's not possible to install only
    the modified plugin, no, instead, it installs everything, including the
    user help containing a huge amount of files...
