In West Germany and other countries the film was released under titles which mean translated back "The Desert of the Tatars". Obviously the editors in these countries missed that the original title does not refer to the actual Tatarian people but to the ancient Greek-Roman mythological "Tartars" (from the ancient Greek word "tartaros"). So "Tartars" in this context is not an outdated spelling of "Tatars", but an intended metaphor referring to the historical idea, that there are a people "coming from hell".
