It's a very rare if at all existing occasion when ARC CPU template is used as is w/o any changes - in the end it's a beauty and competitive advantage of ARC cores to be tailored for a particular use-case - and so it doesn't make a lot of sense to offer template-based "-mcpu" selection. Given for each and every platform we end-up adding quite a few more flags it's logical to move "-mcpu" selection to platform's definition as well which we exactly do here.
