+Add a pre-build hook to remove all build files
+which do not have a corresponding target
+
+This can be used for example to remove the targets
+that have changed name without performing
+a full 'waf clean'
+
+Of course, it will only work if there are no dynamically generated
+nodes/tasks, in which case the method will have to be modified
+to exclude some folders for example.
