Getting JAVA_HOME at runtime

Actually I found a solution by analyzing what javavm is doing:

  make -f /usr/ports/Mk/bsd.port.mk -V JAVA_HOME USE_JAVA=yes

And this will allow the sysadmin to set a version requirement, eg:

  resin2_java_version=1.5+

Will be translated into:

  JAVA_HOME=$(make -f /usr/ports/Mk/bsd.port.mk -V JAVA_HOME USE_JAVA=yes JAVA_VERSION="${resin2_java_version}")

However it slows down a little bit the rc script.
