For linking with -static-libgcj, you must configure with
--disable-libgcj-bc. You will also need to apply this patch:
http://gcc.gnu.org/ml/java-patches/2007-q4/msg00100.html
Note that I have a newer version of the patch that I will be submitting,
but the current version is sufficient to get started with linking with
-static-libgcj.
