bitbake: bitbake-worker: Extra profiling data dump
Currently we get no profiling oversight into either the main bitbake worker process, or the overall parsing before task execution. This adds in extra profiling hooks so we can truly capture all parts of bitbake's execution into the profile data. To do this we modify the 'magic' value passed to bitbake-worker to trigger the profiling, before the configuration data is sent over to the worker. (Bitbake rev: 446e490bf485b712e5cee733dab5805254cdcad0) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
