next-20140529 - 'perf' fails to build on Fedora Rawhide...

[Valdis Kletnieks]

So what did I do wrong with this build of 'perf' (other than
trying to do it on a Fedora Rawhide box updated to last night? :)

(The obvious hack fix is to change the '#define _BSD_SOURCE 1' in util/util.h
to use _DEFAULT_SOURCE instead, but not sure how that plays on older
userspaces, as that was a glibc 2.19 feature that only escaped about
3 months ago....)

[/usr/src/linux-next/tools/perf] make
  BUILD:   Doing 'make -j4' parallel build
config/Makefile:580: No numa.h found, disables 'perf bench numa mem' benchmark, please install numactl-devel/libnuma-devel/libnuma-dev
