    Fix html docs builds · a2d917f3
    Iustin Pop authored
    This fixes the doc builds broken by commit b292b986
    , but is only an
    ugly workaround due to our dependency chain.
    opcodes.py imports (both directly and indirectly) constants.py, which
    imports _autoconf.py. Hence one could say that all .py files have a
    logical dependency on _autoconf.py, since you can't "import opcodes"
    before _autoconf.py is built. So the sphinx rule should depend on
    _autoconf.py as a prerequisite.
    But we can't use a normal prerequisite, since that would cause the
    html docs to be rebuilt whenever _autoconf.py gets rebuilt, i.e. even
    on end-users machines after ./configure; this is bad, and it also
    breaks distcheck (as the html files are not removed in distclean,
    since we do want them distributed).
    So we only add an order-only prerequisite, which does the right thing
    (although our dependency chain is still ugly).
