Generated code is not recreated when patches modify scripts/tracetool/*.py. Typically such patches also modify trace/*.[ch] and the result is build failures when new C code compiles against stale generated code. 2. The timestamp mechanism used to avoid unnecessary rebuilding is broken, it currently requires two make invocations for a full build.
