I can compile it with elfutils-0.137 and some compiling options on RHEL5.
We need the following change in Makefile.

-       $(CC) $(CFLAGS) $(OBJ_ARCH) -o $@ $< -static -ldw -lelf -lz
+       $(CC) $(CFLAGS) $(OBJ_ARCH) -o $@ $< -static -ldw -lbz2 -lebl -ldl -lelf -lz


By the way, do you have any documents/samples for dwfl_XXXX functions ?
I'd like to see them for reviewing this patch.
