+Subject: [PATCH] kconfig: abort configuration 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.
