linuxulator update

[Alex Hornung]

Diablo JDK has never needed the linuxemu, but I think it is built with it.
What I was referring to was the official sun jre/jdk. In any case, jre/jdk
is just one of many things that potentially use linuxemu.

As far as OpenJDK goes, that involves getting gcj, icedtea, etc working
which is a considerable effort. But again, this is not only about java but
in general about the linuxulator.
