Progress: Add initial stand alone builds for both controller and init programs.

Bring in the stand alone build that includes the FLL source files in a build settings file.
The associated fakefile will be updated and tested later.

The config.h files are currently incomplete.

Currently to test the stand alone builds:
  - Use an empty config.h file.
  - Copy the sources from the monolithic FLL package into the sources directory under sources/c/fll/.
  - Build the controller stand alone program via:
    # fake -s data/build/stand_alone/settings.controller build
  - Build the init stand alone program via:
    # fake -s data/build/stand_alone/settings.init build

Due to using an empty config.h file the resulting binary is oversized due to including unneeded code.
This will change once the controller.config.h and init.config.h are appropriately updated.
