[PATCH 20/47] perf evlist: Remove obsolete dummy execve

From: Arnaldo Carvalho de Melo
Date: Wed Aug 07 2013 - 17:22:08 EST

From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

Minor cleanup.

The dummy execve to pre-resolve the PLT is obsolete since
"enable_on_execve" was added. The counters are only
running after the execve anyways. So just remove it.
