Is it a shared library or binary?
Unless you link with --emit-reloc, there is IMHO no way to do this for
binaries as you loose a lot of information for that during the link.
Shared libraries are doable quite easily, e.g. with prelink -r 0xsomeaddr somedso.so
But the code to do all that in prelink is not very short and doing it
in bfd framework would be even harder (prelink uses libelf).
