I hope you MOVE'd it, copying won't help anything since the plan is to get rid 
of the libs stored in /lib/tls.

Three possible reasons:
 - you didn't remove the /lib/tls directory
 - init is statically linked against a tls glibc, you can safely ignore the 
warning if its only init, or recompile it.
 - your compiler generated some code to access tls on its own, and that code 
looks to xen like an nptl glibc. in that case, recompile with 
"-mno-tls-direct-seg-refs" (available in gcc-3.4.4 or newer)


I'm not that familiar with FC4, tho, so the problem might be something 
completely different...
