Subject: [PATCH 14/14] perf tools: Add missing parse_events_error() prototype

From: Arnaldo Carvalho de Melo <acme@...hat.com>

As pointed out by clang, we were not providing a prototype for a
function before using it:

  util/parse-events.y:699:6: error: conflicting types for 'parse_events_error'
  void parse_events_error(YYLTYPE *loc, void *data,
       ^
  /tmp/build/perf/util/parse-events-bison.c:2224:7: note: previous implicit declaration is here
        yyerror (&yylloc, _data, scanner, YY_("syntax error"));
        ^
  /tmp/build/perf/util/parse-events-bison.c:65:25: note: expanded from macro 'yyerror'
  #define yyerror         parse_events_error

  1 error generated.

One line fix it.
