No pb. Thanks for trying. We were seeing the failures only in pretty specific circumstances (particular machine & load conditions etc) The patch remains worth considering IMO. At least, it would be interesting to get feedback from a build-system maintainer on the correctness of the current dependencies. Our understanding is that it is incorrect to have libcc1 depend on maybe-all-gcc in a bootstrapping setup because it can trigger rebuilds of gcc/ components in parallel with ongoing processing of target components (with pre-requisites on stage_current only).
