Replying my own questions, the name of the defconfig is not represented
by SYS_CONFIG_NAME and NAK my own patch here... it will have to be a
different (new?) symbol name and configurable from Kconfig not
necessarily defconfig file name.
I'll improve on the other series "increase detail for dtsi debug output"
and propose a user-configurable dtsi include order that is more suitable.
Thanks for your patience while I learn these programming concepts!
