[PATCH v2 0/5] Perf tool fixes for ARC + uClibc

[Vineet Gupta]

Hi,

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

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.
