Go to menuconfig --> Core (libc, locales) --> kernel tools --> perf

It should just work activating and using it on target, if you set the right 
kernel config options.

(It doesn't work on my target though, I asked about it on IRC lately, but got 
no help. On a at91sam9g20 SoC with 32 MB of RAM leads to perf segfaulting on 
start, and strace leads me to the assumption there's not enough memory. :-/ )
