  perf tools: Make flex/bison calls honour V=1 (2015-05-14 19:27:47 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Add --range option to show a variable's location range in 'perf probe',
  helping in collecting variables in probes when there is a mismatch
  between assembly and source code (He Kuang)

- Show better error message when failed to find variable in 'perf probe' (He Kuang)

- Fix 'perf report --thread' handling and document it better (Namhyung Kim)

Infrastructure:

- Fix to get negative exit codes in 'perf test' test routines (He Kuang)

- Make flex/bison calls honour V=1 (Jiri Olsa)

- Ignore tail calls to probed functions in 'perf probe' (Naveen N. Rao)

- Fix refcount expectations in map_group share 'perf test' (Arnaldo Carvalho de Melo)

Build Fixes:

- Fix 'perf kmem' build due to compiler thinking uninitialized var is
  being accessed (Arnaldo Carvalho de Melo)

- Provide le16toh if not defined, to fix the libtraceevent build on
  older distros (Arnaldo Carvalho de Melo)

- Fix 'perf trace' build on older distros by providing some CLOEXEC, NONBLOCK
  defines (Arnaldo Carvalho de Melo)
