You're seriously telling me that you check every line of the oldconfig
output in case of the problem?
If it makes you feel better, you can rerun oldconfig after the
silentoldconfig, but the output is practically useless.
It would actually be a lot better if you ran a diff between the old config
and the new config and add this to the build output, only the contents of
the .config file is relevant to kbuild and if something went wrong, the
real differences would be easily visible.

Even if they sound similiar they are not the same. e.g. I'm working on
patches to integrate split config step, so it will do a bit more than
normal config targets (but it remain a valid make target). The
silentoldconfig target is an automatic target which is also used by kbuild
to verify the config consistency.
The situation is very simple, we have automatic config targets (like
silentoldconfig or all*config) and we have interactive config targets
(like config, xconfig, oldconfig).
I'm very much interested to improve the situation of the automatic
targets to help automatic builds, but just printing useless information
adds no value. If you don't trust that silentoldconfig does the right
thing, you can't trust oldconfig either.
