Here is a patch to do that. Now, neither the front-end nor the runtime will
be built unless "--enable-languages=java" is explicitly given to configure.

It also removes libgcj from the noconfigdirs on several platforms that we
ought to build on. Wishful thinking perhaps, but this will make life a
little easier for those who want to fix up the ports, and, given the above,
won't affect those who don't. Actually, I'm tempted to remove libgcj from
all the target noconfigdirs?
