John Ericson d349f9a340 cc-wrapper: Use stdenvNoCC to build
cc-wrapper may wrap a cc-compiler, but it doesn't need one to build
itself. (c.f. expand-response-params is a separate derivation.) This
helps avoid cycles on the cross stuff, in addition to removing a
useless dependency edge.

I could have been super careful with overrides in the stdenv to avoid
the mass rebuild, but I don't think it's worth it.
