target: Remove "-variant" argument

Browse Source 
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.
