jitterdebugger binary package in Ubuntu Noble s390x

 jitterdebugger measures wake up latencies and able to store all samples for
 post-processing.
 .
 It starts a thread on each CPU which programs a timer and measures the time it
 takes from the timer expiring until the thread which set the timer runs again.
 .
 This tool is a reimplementation of cyclictest. It doesn't have all the command
 line options as cyclictest which results are easy to get wrong
 and therefore an invalid latency report.
