Please see my reply on another post from Thomas:

It's not like a build failure of perf tools, it's just a result of
feature test so should not affect the build of perf itself, right?  Why
it confuses us is that we don't show any compile message if -s option is
given to make, so I posted a patch to hide CHK and above failure message
when -s option is specified.

Thanks,
Namhyung
