ARC: rework setting of ARC CPU specific compiler options
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.

+ For nSIM we allow to set custom arc-specific compiler options

+ target is used for representing targets without fixed CPU version

+ This variable takes space separated compiler options list.
