PS3, Line 9: This improve ccache hit rate
> is there a better argument to be made for moving […]

The motivation was to split these strings away from build/config.h to build/board_id.h, which will only be an input for lib/identity.c. I am still experimenting with ccache to see if I am able to transform hits from "preprocessor hit" to "direct hit", latter is typically much faster and may result with smaller memory footprint.

I have not inspected the binaries that closely yet to check if constant Kconfig strings currently appear twice expanded in the binaries. Output of "objdump -r -d" may actually appear nicer since the references are to symbolic names found in source.
