// The use of runtime.GOOS and runtime.GOARCH makes sure that
// a cross-compiled compiler expects to compile for its own target
// system. That is, if on a Mac you do:
//
//	GOOS=linux GOARCH=ppc64 go build cmd/compile
//
// the resulting compiler will default to generating linux/ppc64 object files.
// This is more useful than having it default to generating objects for the
// original target (in this example, a Mac).
