[PATCH v2] perf tools: Fix build with bison 2.3 and older.

From: Vinson Lee
Date: Wed Feb 13 2013 - 16:49:20 EST

The %name-prefix "prefix" syntax is not available on bison 2.3 and
older. Substitute with the -p "prefix" command-line option for
compatibility with older versions of bison.

This patch fixes this build error with older versions of bison.

BISON util/pmu-bison.c
util/pmu.y:2.14-24: syntax error, unexpected string, expecting =
