No, you don't need to do that.

The TLS refs problem happened because 32-bit Xen and glibc both want to do 
crazy things with the processor's segmentation hardware.  32-bit Xen needs 
the segmentation for its own protection.

64-bit Xen doesn't protect itself using segmentation, so it's not necessary to 
do anything to prevent a conflict with glibc.

Enjoy!

Cheers,
Mark
