I can't speak for the SuSE package, but on FC5 glibc picks up the right
TLS version automatically too.  You can check it's working with

        $ cat /proc/self/maps

which on my local i386 dom0 shows:

                /lib/i686/nosegneg/libc-2.4.so

as the libc in use, showing it is detecting and using the "nosegneg"
Xen-friendly version automatically.  SuSE may well be using a similar
scheme.
