    Add Cflags and Include paths to pre_build_cmds environment
    
    Add the CFLAGS and INCLUDE_PATH as used by newt to the environment when
    starting a pre_build_cmd. I need this to execute rust bindgen correctly.
    This program will parse the mynewt headers and generate rust code from
    that and therefore it needs the correct c-flags and include paths.
