Not particularly.  The OS could care less.  Take linux, for
example (or at least my understanding of it).  

The C startup code minimally knows how to dynamically link in
/lib/ld.so  (This makes updating stuff easier, as the C startup
code will rarely change, in this aspect).  ld.so then has enough
intelligence to do the rest of the linking.  

Just need enough intelligence in the tools to build such
critters.
