Sure, but I doubt it makes sense to put every tool in there.
For bigger ones like perf, and IMO also cpupower it makes
sense to package them separately.

Yep, I double checked: cpupower builds on ppc here too.

It would really be great if this gets packaged separately.
Find attached my .spec file.
If someone looks at this, he can freely take over whatever he wants.

This tool is to make access to the Linux kernel's processor power subsystems
like CPU frequency switching (cpufreq) or CPU sleep states (cpuidle) for users
and userspace tools easier.

Contains libcpupower and soon possibly other CPU power related
C libraries.

Obsoletes: cpufrequtils-bench < %version
Provides: cpufrequtils-bench = %version
%description bench
Helps to test the condition of a given kernel cpufreq
governor (e.g. ondemand, userspace, conservative) and the cpufreq HW driver
(e.g. powernow-k8, acpi-cpufreq, ...).
For that purpose, it compares the performance governor to a configured
powersave module.
