It turns out that if I set use_grobner: false, then it uses a resultant
method and algsys returns
empty, same as Maxima.
So I was wrong in thinking this could not have been a bug in old systems.
I still think that resultants should work if some bug were removed, but
so can Grobner bases; the fastest should
be triangularization, if it is applicable.
