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

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! -- Best regards, Gioh Kim
