I haven't checked this specific problem, but the exec-shield problem 
was that there is a hole between data and bss.  unexelf.c assumes these 
are next to each other.  It should be possible to make two data 
sections, one for the original data and one for the original bss, that 
are mapped to two different addresses when dumping.  But then sections 
in the dumped image needs to be expanded and that is tricky as all 
sections after needs to be moved as well.
