Add function __ppc_get_timebase() to directly read the Time Base register.
This is required for applications that measure time at high frequencies
with high precision that can't afford a syscall.

Tulio,


Have you given any consideration to contributing a manual page for
this to the man-pages project?

Yes. It's already on my task list.


Thank you,
