There should be nothing in /lib/tls (now /lib/tls.disabled), the
standard glibc in Fedora now uses unconditionally tls.

The standard Fedora kernel installs this ld.so configuration file:
$ cat etc/ld.so.conf.d/kernelcap-2.6.20-1.2952.fc6.conf 
# This directive teaches ldconfig to search in nosegneg subdirectories
# and cache the DSOs there with extra bit 0 set in their hwcap match
# fields.  In Xen guest kernels, the vDSO tells the dynamic linker to
# search in nosegneg subdirectories and to match this extra hwcap bit
# in the ld.so.cache file.
hwcap 0 nosegneg

Create that file, and then run ldconfig. The system should now use the
proper libraries for Xen.

If it doesn't, then the xen kernel doesn't change the vDSO as fedora's
does. In which case, copy the nosegneg versions over the standard ones.
