In order to incorporate external blobs into
    CBFS besides MRC have a notion of a reference code
    blob. By selecting HAVE_REFCODE_BLOB and providing
    the file name the refcode blob will be added to
    cbfs as a stage file.

    BRANCH=None
    TEST=Using this option and other patches able to build,
         boot, and run blob code.
