Add a WITHOUT_LIBJAVA knob, which disables building libgcj and thus saves
quite some build time and also disk. Make this the default on sparc64 and
ia64 where libgcj has not been ported to and thus fix long-standing packaging
issues on these two platforms.
On the way, update to the 20040322 snapshot of GCC 3.3.3.
