   4 Subject: [PATCH] kconfig: abort configuration on unset symbol
   5
   6 When a target configuration has unset Kconfig symbols, the build will
   7 fail when OpenWrt is compiled with V=s and stdin is connected to a tty.
   8
   9 In case OpenWrt is compiled without either of these preconditions, the
  10 build will succeed with the symbols in question being unset.
  11
  12 Modify the kernel configuration in a way it fails on unset symbols
  13 regardless of the aforementioned preconditions.
