added optional --with-jvm=

[Grzegorz B. Prokopski]

This patch adds --with-jvm= configure option handling.
It has NO effect unless it's explicitely used.

2004-03-27  Grzegorz B. Prokopski <address@hidden> 

        * configure.ac: Added --with-jvm= handling defaulting to none.
        * acinclude.m4: Don't build .zip for --with-jvm=sablevm.
