Dear Maintainer,

#error You need to define CycleTimer for your OS and CPU
The attached patch adds a bit of code to access the interval timer on hppa.
This fixes the build error.
Note that a 32-bit counter value is returned when the processor is running
in narrow mode. The counter nominally runs at the processor frequency.
Regards,
Dave Anglin
