Fixing a crash when showing GTK dialogs on Linux on Debug builds.

Fixing a crash when showing GTK dialogs on Linux on Debug builds.

This problem was introduced several months ago (crbug.com/462689) and
causes a crash when a GTK dialog is displayed on debug, non-component
builds on Linux.  The fix is to include some additional linker flags in
this scenario (see libgtk2ui target as another example of this
workaround) which allows the framework to run correctly.
