OK, I have applied this set for 5.5.

I do worry that this all looks a little complex and fragile.  I wonder if
there's a way that we could set up some sort of dependency chain that
would just tell make not to run the docs builds in parallel with anything
else?  That is more-or-less the effect of what we're doing anyway.

Meanwhile, though, this seems to work, so let's go with it :)

Thanks,
