New Revision: 123869

URL: http://svn.digium.com/view/asterisk?view=rev&rev=123869
Log:
The RDTSC instruction was introduced on the Pentium line of microprocessors,
and is not compatible with certain 586 clones, like Cyrix.  Hence, asking for
i386 compatibility was always incorrect. See http://en.wikipedia.org/wiki/RDTSC
(Closes issue #12886)
