Subject: [PATCH] util/kconfig: Ignore extra symbols in configs instead of
 failing

When updating an old .config file that has a symbol that has been
removed from the current Kconfig tree, kconfig will generate a warning
and fail to save the updated file.  This is incredibly annoying, and
not the goal when trying to eliminate Kconfig warnings.

Instead of generating a warning, just print a message that it's being
ignored.  This will remove the offending symbol, while allowing the
updated config file to be saved.

Split the change from 1 line to 3 lines to keep it at 80 characters.
