You can't build openjdk from source without a bootstrap JDK.  So, whatever
machines you have, at least one of them will have to have a compatible
working JDK on it.  You could, for example, install Solaris on the Sparc64
machine and run a JDK there, but you have to have _something_ with a
running JDK.  Also, since the bootstrap JDK isn't on the same machine you're
building on you'll have to use the technique described in the post I sent a
link to above.
