Bulding an XXX language run-time library is a very special case. You
can't build an XXX language run-time library, assuming the XXX language
compiler is fully functional.  If upstream libtool can support it, it
is great. Otherwise, we have to do one of these 4:

1. Drop Java.
2. Drop libtool for libjava.
3. Hack libtool for libjava.
4. Hack libjava configure to work around the libtool problem.

I proposed #3 with a simple and straightforward work around. We may
have to keep it around forever.
