Moved the hardcoded postBuild hook from the builder to generic.nix: Some old kernel (such as 2.6.15) did not yet support the unifdef target. As a result, compiling them with the current Linux builder leads to a failure. Fixed by moving this hook as argument of the top-level function of generic.nix. This allows some kernel nix codes to overrides its default value. svn path=/nixpkgs/trunk/; revision=27708
