Benjamin Herrenschmidt d8e998c58a [PATCH] ppc32: Tell userland about lack of standard TB 
Glibc is about to get some new high precision timer stuff that relies on
the standard timebase of the PPC architecture.

However, some (rare & old) CPUs do not have such timebase and it is a
bit annoying to have your stuff just crash because you are running on
the wrong CPU...

This exposes to userland a CPU feature bit that tells that the current
processor doesn't have a standard timebase.  It's negative logic so that
glibc will still "just work" on older kernels (it will just be unhappy
on those old CPUs but that doesn't really matter as distro tend to
update glibc & kernel at the same time).
