Right, I can't see a reason why we would need to compile a single object 
different for qemu-img and qemu-nbd.  I think there's something fowl there.

Half solutions often mask the underlying problem because people think 
it's fixed.  I only think it's appropriate to do this sort of thing if 
the amount of work to do it right is prohibitively high.  In this case, 
someone just has to do a quick audit of the Makefile and respective .c 
files or Laurent just needs to explain why he did it that way :-)
