I'm afraid I might have missed what you've posted
some time ago about this 'new' and preferred
relocation mechanism.  Could you provide me a pointer
? 

I didn't knew that bfd_get_relocated_section_contents
was broken on some architectures.  As I understand it,
the ..._final_link routine you're referring to handles
much more than what's needed for GCL, which basically
is what bfd_get_relocated_section_contents provides. 
bfd_final_link not only handles loading the properly
relocated section contents in memory, but is also
responsible for creating the output symbol table and
other stuff that we might not be interested in.  But
this is just my present thought on it.

I haven't had a chance to look at elflink.h yet. 
Maybe you could tell me what the logic in there is. I
believe this could save me a great deal of time if I'm
ever to look at this file.

And what did you do to get this error message ?
