This instruction has been irrelevant since FC5 - we remove this warning
message from the kernel. The dynamic linker will automatically pick the
correct GLibC library.

Even with that though, certain processes will still print TLS messages
because they are statically linked (kudzu, prelink, init) or are just
doing their own crazy stuff (mono, beagled). The majority of apps will
run correctly.

The only gotcha if you're using XenSource's RPMs instead of the official
Fedora RPMs for kerenl-xen, is that you'll be missing a linker config
file in /etc/ld.so.conf.d/ containing  'hwcap 0 nosegneg'

If every single app is causing thousands of TLS message to be spewed to
the console, then its not working - if you only see a handful of messages
from the apps i mention above, then it is working.
