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.
