Cross build support doesn't require that you break things like that.  Never had, and never will.  The FreeBSD version is irrelevant to cross building, so bootstrapping checks are still needed.  In the cross build, the bootstrapping OS version will be 0 and we'll build everything we need (possibly more than we would bootstrapping from supported FreeBSD versions).

You can accomplish this without blowing away the conditionals.
