I don't have examples readily at hand.  However, what was then called
"complex relocation" was supported, AND was used in real world
software, in DEC assemblers going back all the way to Macro-11 back in
1974 or so.  In other words, ELF apparently has trouble representing
things that other binary formats have handled for 30 years.
