- use cores+1 threads
- do not clean build directories
- separate build directories for blender and blenderplayer
This should make compilation much faster and buildbot rebuild tag could
happen more often
- Use the same config as we're using for release builds
- Added stipping (maybe it should be generalized)
- Not software gl packing, bot would be easy to add
Note, that you should have special environment to create
proper linux builts (which would work for everybody)
