wxwidgets.eclass: Define -DNDEBUG when building against wxGTK:3.0 In wxGTK 3.0 debugging support is always enabled in the library and it's up to packages to state if they want to use it or not. When enabled this makes warning dialogs pop up any time an assertion is encountered, which isn't very user friendly. This disables that behavior by adding -DNDEBUG to CPPFLAGS unless the package has a debug USE flag and it is enabled.
