After some discussion with some others working on linux, we've decided that we
should add a BASE_GTK define to build_config.h.  You could imagine some day
there being a BASE_QT that would be the other side of this.  A lot of the
OS_LINUX || OS_BSD could then be converted to BASE_GTK.

Please add a description in build_config.h where you define it that explains the
difference between BASE_GTK and TOOLKIT_GTK.  BASE_GTK is for underlying system
features like clipboards and rectangles, whereas TOOLKIT_GTK is the UI toolkit
(since it's possible to have BASE_GTK and TOOLKIT_VIEWS).
