Set the 32-bit ARM HZ value to a default value of 100 if the kernel
was not configured with CONFIG_IKCONFIG.  Without the patch, the
initial system banner and the "sys" command show "UPTIME: (cannot
calculate: unknown HZ value)", the "ps -t" option shows "RUN TIME:
(cannot calculate: unknown HZ value)", and the "timer -r" option
kills the crash session with a floating point exception.
