Create a .cfg file containing the CONFIG options used to build
At present CONFIG options are split across Kconfig and board config headers
files. Also we have multiple files containing these CONFIG options.
In order to see exactly what is being used for building, create a .cfg
file which holds these options as reported by the C preprocessor.
