Is there a specified invocation order for the segments?

Does the call happen immediately after relocations for an object are 
processed, or only after relocations for all objections are processed?

If the latter, why can't you use the existing ELF constructor mechanism 
for this?  As far as I understand it, the call to __gnu_mbind_setup 
would just happen before the constructor calls.
