perf tools: Fix bison-related build failure on CentOS 6
The YYLTYPE_IS_TRIVIAL is defined in the Build file, but unlike
pmu-bison.c, gcc complained about it for parse-events-bison.c:
CC util/parse-events-bison.o
In file included from util/parse-events.y:16:
util/parse-events-bison.h:101:1: error: "YYLTYPE_IS_TRIVIAL" redefined
<command-line>: error: this is the location of the previous definition
make[3]: *** [util/parse-events-bison.o] Error 1
Comments from Jiri Olsa:
"Reason is the parse error handling that was added just recently: it
adds YYLTYPE type (which is not present in pmu-bison.h), so
YYLTYPE_IS_TRIVIAL gets redefined, which is ok in F20 that handle the
error via '-w' option, but it's not ok for RHEL6 where the '-w' does not
work for this kind of error."
