I wish it were easier! The quick-and-dirty way is to remove
prefix/lib/libgcj.so before you link.
Otherwise experiment with -Bstatic/-Bdynamic, roughly:
GCJ = gcj
JVGENMAIN = /opt/gcc/lib/gcc-lib/i686-pc-linux-gnu/3.5-tree-ssa/jvgenmain
%.o: %.java
	$(GCJ) $(GCJFLAGS) -c $< -o $@
Hello: Hello.o Hello_main.o
	gcc -shared-libgcc Hello.o Hello_main.o -o Hello \
		-Wl,-Bstatic -lgcj -Wl,-Bdynamic -lm -lpthread -ldl
Hello.o: Hello.java
Hello_main.o: Hello_main.c
Hello_main.c:
	$(JVGENMAIN) Hellomain $@
