At a guess (untried by myself), it might be possible to use objcopy to
add/change the rpath information __after__ the build is otherwise complete.

I.E: For the case where the rpath information added is for the target's use,
rather than the build host's use.

I do not know for certain if objcopy can access or change the rpath 
information field in an object, I have never seen or read about it being done.
