Hi,

This series based off linux-next of 20150105 allows us to build/use perf
for ARC with uClibc based userland.

v3: Changes since v2 [2]
* 1/5 : Ack from Jiri
* 2/5 : no changes
* 3/5 : sys/syscall.h included [Jiri]
* 4/5 : no changes
* 5/5 : -lpthread added to link target [Jiri]
* {1,5} : Changelog updated so scissor lines don't start at column 1

v2: Change since v1 [1]
* [1-3]/5 : no changes
* 4/5 : Make perf_evsel__alloc_id agnostic of zero threads [Namhyung Kim]
* 5/5 : Add missing test file

v1:
* 1/5 is really a resend of old patch posted by Alexey a while back
* 2/5 is uClibc build spew seen on ARM as well
* 3/5 likewise
* 4/5 is uClibc config specific
* 5/5 is uClibc pthread library flavour specific
It adds a stub for pthread_attr_setaffinity_np
I can rework it to disable the futex tests altogether if people think that is
cleaner

Please review and consider applying.
W/o these perf doesn't build and/or work for ARC.
