[PATCH 2/2] kernel-shark: Add make BUILD_TYPE=X gui to change how the gui is made

[Steven Rostedt <rostedt@goodmis.org>]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Add a option to the Makefile called "BUILD_TYPE" that is passed to the CMake
commonds to change how kernelshark is built. The current options are:

 make BUILD_TYPE=Debug gui          - for "-g" option
 make BUILD_TYPE=Release gui        - for "-O3" option
 make BUILD_TYPE=RelWithDebInfo gui - for "-g -O2" option (default)
 make BUILD_TYPE=MinSizeRel gui     - for "-Os" option

By default, BUILD_TYPE is set to RelWithDebInfo.

Also change the CMakeLists.txt to use RelWithDebInfo as the default
instead of just Debug.
