perf tools: Add "reject" option for parse-events.l
Arnaldo reported broken builds in some distros using a newer flex
release, 2.6.4, found in Alpine Linux 3.6 and Edge, with flex not
spotting the REJECT macro:
CC /tmp/build/perf/util/parse-events-flex.o
util/parse-events.l: In function 'parse_events_lex':
/tmp/build/perf/util/parse-events-flex.c:4734:16: error: \
'reject_used_but_not_detected' undeclared (first use in this function)
It's happening because we put the REJECT under another USER_REJECT macro
in following commit:
9445464bb831 perf tools: Unwind properly location after REJECT
Fortunately flex provides option for force it to use REJECT, adding it
to parse-events.l.
