Log Message:
Remove bogus ONLY_FOR_PLATFORM. This package is just a .jar file and
some docs, so it'll run anywhere there's a suitable JVM.

It seems that the ONLY_FOR_PLATFORM setting was originally inserted to
conservatively limit the package to platforms that had or where pkgsrc
could provide a JVM, and then both persisted after that was no longer
necessary and got cargo-culted elsewhere.
