For this to work, the BUILD_JDK needs to be ready for usage. In a normal native build, this means that the exploded-image-optimize target needs to be done. This dependency is however missing, so we sometimes get errors like this:

The default BUILD_JDK is just the exploded image. When cross compiling, we either create a BUILD_JDK explicitly, or we use an externally provided BUILD_JDK. By introducing this virtual target, we don't need to sprinkle these conditionals in quite so many places.
