Remove this underutilized feature. Despite the fact that a lot of configs specifies a arbitrary "variant", only the xscale target actually defines any. In the case of xscale, the use of -variant is dubious since 1) it's used as a redundant irlen specifier, 2) it carries a comment that it doesn't really need it and 3) only two xscale configs even specify it. If there's a future target that needs a variant set, a target specific option could be added when needed.
