Fixes for perf/urgent:

. Properly handle ~/.debug, the build id cache, when it is a symlink,
   fix from Chanho Park
 
 . Fixes for the parser generation process, from Jiri Olsa and Namhyung Kim
 
 . Fix build when NO_GTK2 is specified, From Stephane Eranian
 
 . When a machine is not found, bump the relevant error stat but return
   0, so that we correctly move to the next perf event. Fix from Jiri Olsa
