In addition to what Jakub said, you can't use DW_FORM_ref4 this way. 
Consumers don't expect inter-compilation-unit references here.  Use
DW_FORM_ref_addr instead.

Alan posted initial patches for editing dwarf2 information in binutils
a while ago.  You'd have to do something very differently to change the
content of DIEs in the way you need to do here... but they might still
be a useful starting point.  Assuming you want to do this at some point
in binutils and not in elfutils; elfutils isn't really on-topic for
this list.
