Subject: [PATCH] kconfig: suppress "configuration written to .config" for
syncconfig
The top-level Makefile invokes "make syncconfig" when necessary.
Then, Kconfig displays the following message when .config is updated.
#
# configuration written to .config
#
It is distracting because "make syncconfig" happens during the build
stage, and does nothing important in most cases.
