[PATCH v6] perf tools: Separate out GTK codes to libperf-gtk.so

From: Namhyung Kim
Date: Fri Sep 13 2013 - 02:28:15 EST

Separate out GTK codes to a shared object called libperf-gtk.so. This
time only GTK codes are built with -fPIC and libperf remains as is.
Now run GTK hist and annotation browser using libdl.
