[PATCH 1/5] perf tools: Fix -C option for record command

From: Jiri Olsa
Date: Mon Feb 25 2013 - 04:53:41 EST

Currently the -C option does not work for record command,
because of the targets mismatch when synthesizing threads.

Fixing this by using proper target interface for the
synthesize decision.
