    sphinx: stop using parallel mode
    
    Noticed that the documentation build can stuck on a machine with
    many cores (160) and I identified a real sphinx problem:
    https://github.com/sphinx-doc/sphinx/issues/10969
    
    Note the parallel can help just for some manuals and it is not critical
    for us.
    
    ChangeLog:
    
            * doc/Makefile: Disable -j auto.
