Subject: [PATCH 13/16] perf tools: Rename flex conditions to avoid name conflicts

From: Robert Richter <robert.richter@...aro.org>

These define's may cause conflicts with other definitions:

 #define INITIAL 0
 #define mem 1
 #define config 2
 #define event 3

Prefix them with cond_* to avoid this.
