[PATCH] [Signed-off] kconfig: document oldnoconfig to what it really does in conf.c

[PATCH] [Signed-off] kconfig: document oldnoconfig to what it really does in conf.c

[Adam Lee]

As 67d34a6a391369269a2e5dba8a5f42cc4cd50231 said, the make target
'oldnoconfig' is a misnomer. It doesn't set new symbols to 'n', but
instead sets it to their default values.

This patch fixes the document in conf.c, and will submit another patch
to replace 'oldnoconfig' to 'olddefconfig'

Hi,

I think we should apply this patch, any comment?

I was confused by the different documents of `make help` and usage of
"scripts/kconfig/conf.c" before I got through conf.c and checked the git
log. Others maybe confused too. So I think we really should apply this
patch at least.

As regards whether that target should be renamed to 'olddefconfig', we
can discuss it at another thread.

Thank you.

Sorry for the delay. I applied it to kbuild.git#kconfig now.
