Ok, let me ask this in a different way ;-)

Is there a _complicated_ way to add an RPATH to an already existing
executable using binutils? 

I looked at libbfd for half an hour, and it seems like I could just
read the executable file using bfd_openr and friends, add the rpath to
the private data and write it back. But I find it hard to believe that
nobody else has had a need for such a program before. 

Is libbfd capable of doing this or is more trickery involved that I am
not aware of?
