Initial support of linux 32/64 bit for buildbot:

- 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)
