Subject: [PATCH 4.19 07/43] perf tools: Use %define api.pure full instead of %pure-parser

From: Jiri Olsa <jolsa@...hat.com>

commit fc8c0a99223367b071c83711259d754b6bb7a379 upstream.

bison deprecated the "%pure-parser" directive in favor of "%define
api.pure full".

The api.pure got introduced in bison 2.3 (Oct 2007), so it seems safe to
use it without any version check.
