two possibilites... you have created the initrd at a time where /lib/tls was 
activated without a special libc6 version and that's why you get this 
warning, or the libc6 package you compiled is missing something. I think 
because glibc is older in sarge you have to patch it and not just add a 
compiler flag. But I am not a glibc maintainer and can't help you really.

I hope you haven't installed the libc6 package mentioned in this thread, 
because this was only meant to be for sid and is not working as expected 
anyways...
