-Add a pre-build hook to remove build files (declared in the system)
-that 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.
-
-Make sure to set bld.post_mode = waflib.Build.POST_AT_ONCE
