Yeah, let's get rid of the complexity. The script originally was
intended to be usable independently of the `Makefile`, but in the end
we don't really use it like that.

In fact, now we should probably add a warning/error if somebody calls
it directly (and/or set defaults for the variables). I can send a
patch for that on top of this one.

There is a small functional change, in that we will be making an
unneeded call to `cc-version.sh` and another to `$CC` for the Kconfig
case (i.e. the previously non-verbose case), but that seems like a
fine price for the simplicity.

Could you please remove the comment at the top? i.e.:

    #
    # Pass `-v` for human output and more checks (as warnings).

With that:

If you want me to take it, please let me know.
