perf tests: Fix build on older systems where 'signal' is reserved (2016-02-15 17:33:26 -0300)

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

User visible:

- Do not print trailing spaces in the hists browser (top, report) to
avoid line wrapping issues when long C++ demangled functions are
sampled (Arnaldo Carvalho de Melo)

- Allow 'perf config' to show --system or --user settings (Taeung Song)

- Add better warning about the need to install the audit-lib-python
package when using perf python scripts (Taeung Song)

- Fix symbol resolution when kernel modules files are only in the
build id cache (~/.debug) (Wang Nan)

Build fixes:

- Fix 'perf test' build on older systems where 'signal' is reserved (Arnaldo Carvalho de Melo)

Infrastructure:

- Free the terms list_head in parse_events__free_terms(), also unlink the entries
when deleting them (Wang Nan)

- Fix releasing event_class in 'perf data' fixing integration with
libbabeltrace (Wang Nan)

- Add EXTRA_LDFLAGS option to Makefile (Zubair Lutfullah Kakakhel)
