bitbake: bitbake-worker: Drop BBHASH variables
Iterating through and calling setVar on this number of variables has significant overhead in the profiling data. By not setting this, we save 3,000 calls to setVar which gives a noticeable improvement to the speed of task execution. The BBHASH variables have since been replaced by accessing that data through the siggen code and going forward, that is the preferred way work with it. (Bitbake rev: 92526eadd09d19938762290e0492076174367583) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
