Hi Bernd,
please have a look at the nptl branch where already is the updated _dl_find_hash
for NPTL using the same extra parameter you need. There is also a wrapper
around it as suggested by Jocke.
I think there is a way to use the interface for nptl into your case.
In these days I'm able to check the code.

Carmelo
