------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: kbuild: disable -Wformat-truncation warnings by default
With x86 allmodconfig, we currently get 233 -Wformat-truncation warnings,
which makes the entire warnings rather useless.
This turns off the warning by default, unless we specify W=1 or higher
