Well, you could recompile glibc with the TLS support turned off. And
make sure that your /etc/ld.so.conf.d/ did not get oddnesses done, or
some LD_* variables don't make things look in /lib/tls.disabled,
although that seems unlikely.
Hmm... that would be ok as well, however similar situation has never arised with versions prior to centos 5. I have numerous servers running centos 4.5, and none of them have similar problems. Atleast by renaming the tls directory it should stop giving the error.
P.S. : The directory /lib/tls is empty, so it actually shouldn't make any difference at all.
