Subject: Use --enable-sjlj-exceptions when configuring gcc so that exception
 handling   works for dynamicly linked executables.  Only tested so far on
 i386 with   gcc 3.3.2.  But combined with the latest ldso updates, I can now
 get a   dynamicly linked java helloworld app to run. Add a config toggle for
 building gcj and libgcj.  The build runs fine   through gcc-final but
 currently requires hand interventions to build   gcc-target.  Again, only
 tested so far on i386.
