Change subject: Kconfig: Need to escape variable uses for new kconfig

Patch Set 1:
> There are some of these which could be expanded in Kconfig. Do we want to escape them as well?

The context in which kconfig runs is less well guarded. Binding them all in one place (the build system) helps with debugging and with reproducible builds.
