Hi, Namhyung
After I pulled new changed source codes from 'perf/core' branch
(https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git)
,when I compiled perf I've had a problem with error messages as below.
(I'm using as below
system : Ubuntu 14.04.2 LTS 64-bit
kernel version : 3.13.0-40-generic)
==================
taeung ~/git/tip/tools/perf
:> make -j4
...(omitted)

==================
But I modified 'tools/perf/config/feature-checks/Makefile' as Jirka said
(https://lkml.org/lkml/2015/1/12/216)
so I was able to compile perf.
diff --git a/tools/perf/config/feature-checks/Makefile

Is this patch right ?
Thanks,
