perf tools: Define _GNU_SOURCE on pthread_attr_setaffinity_np feature check (2015-02-11 17:38:55 -0300)

----------------------------------------------------------------
perf/core improvement and fixes:

User visible:

- No need to explicitely enable evsels for workload started from perf, let it
be enabled via perf_event_attr.enable_on_exec, removing some events that take
place in the 'perf trace' before a workload is really started by it.
(Arnaldo Carvalho de Melo)

- Fix to handle optimized not-inlined functions in 'perf probe' (Masami Hiramatsu)

- Update 'perf probe' man page (Masami Hiramatsu)

Infrastructure:

Arnaldo Carvalho de Melo (4):
- Introduce {trace_seq_do,event_format_}_fprintf functions to allow
a default tracepoint field list printer to be used in tools that allows
redirecting output to a file. (Arnaldo Carvalho de Melo)

- The man page for pthread_attr_set_affinity_np states that _GNU_SOURCE
must be defined before pthread.h, do it to fix the build in some
systems (Josh Boyer)

- Cleanups in 'perf buildid-cache' (Masami Hiramatsu)

- Fix dso cache test case (Namhyung Kim)

- Do Not rely on dso__data_read_offset() to open DSO (Namhyung Kim)

- Make perf aware of tracefs (Steven Rostedt).

- Fix build by defining STT_GNU_IFUNC for glibc 2.9 and older (Vinson Lee)

- AArch64 symbol resolution fixes (Victor Kamensky)
