Only after it's released, and presumably only after it's available
in some distribution. Glibc is less than friendly to install by
the average user; less so than gcc even.

It wouldn't if you exported the __stack_guard_value variable all of
the time, rather than 100% reliance on the tls magic. In that case
glibc becomes forward compatible with libgcc's implementation.
