Should I build the perf again when I change the kernel options?

[Gioh Kim]

Hi,

Should I build the perf again when I change the kernel options?

I have 4.14.34 kernel on my desktop and I built perf for my self.
I'd like to change some options.
Should I rebuild perf perf again?

And another case.
If there are two machines that have the same kernel version and
different kernel options.
Should I build the perf for each machines?
Or can I build the perf on one machine and use it on another machine?

Thank you in advance!
