Hmm, yes from one pov this feature is useful for out-of-c/r user,
from another pov -- we will have to ask users to turn on additional
CONFIG entries (which i'm sure not set by default in wide range of distros).
Thus it seems less paiful way is either make it obj-(CHECKPOINT_RESTORE)
as you proposed, or obj-y by default. The last can't be undone, so I'll
prepare the patch for obj-(CHECKPOINT_RESTORE) I think.
