From: David Bauer <mail@david-bauer.net>
Subject: Kconfig: exit on unset symbol
When a target configuration has unset Kconfig symbols, the build will
fail when OpenWrt is compiled with V=s and stdin is connected to a tty.
In case OpenWrt is compiled without either of these preconditions, the
build will succeed with the symbols in question being unset.
Modify the kernel configuration in a way it fails on unset symbols
regardless of the aforementioned preconditions.
