we were using icecream a year ago and we set ICECC_CARET_WORKAROUND env
variable to 0 (in set_icecc_env() in icecc.bbclass). The default is 1 and it
causes a local rebuild when any warning is emitted.

I don't have exact numbers, but the extreme case was opencv. There was so
many warnings that distributed build on ~10 threads was slower than local
build on 4 threads.

I know that it is some kind of configuration, but I would set the default to
0. Or do it at least configurable.

Thanks for work on that, I'm keen to use it in our environment.
