Ignore some of my comments, I didn't see the attached patch (it seems
it was not inline), making it harder to comment on.

 * On the clean target

   I see that all the stamps are removed. So this will trigger
   basically a reconfigure + rebuild of all packages. Is this what we
   want ?

   Same question as before: is removing the target/ directory without
   removing the staging/ directory really safe ?

   Removing $(IMAGE) will not do anything, since $(IMAGE) is the prefix
   for the filesystem images. I.e, the tar image is $(IMAGE).tar.
   Shouldn't we just remove $(BINARIES_DIR) ?

 * Your description mention realclean, but the patch implements dirclean

 * Detail: in dirclean (realclean ?), shouldn't we erase $(BASE_DIR)
   simply, instead of erasing all individual directories it contains ?

 * On distclean: removing the BUILD_DIR and TOOLCHAIN_DIR is already
   done by dirclean, on which distclean depends. If clean removes
   BINARIES_DIR as suggested above, we can also drop this clean here.

 * Documentation (both 'make help' and the HTML documentation)

Again, thanks a lot for working on this issue.
