Subject: [PATCH 2/2] perf, tools: Allow to force redirect pr_debug to stderr.

From: Andi Kleen <ak@...ux.intel.com>

When debugging the tui browser I find it useful to
redirect the debug log into a file. Currently it's always
forced to the message line.

Add an option to force it to stderr. Then it can be
easily redirected.
