    [nvptx] Build libraries with misa=sm_30
    
    In gcc-11, when  specifying -misa=sm_30, an executable may still contain sm_35
    code (due to libraries being built with the default -misa=sm_35), so it won't
    run on an sm_30 board.
    
    Fix this by building libraries with sm_30, as was the case in gcc-5 to gcc-10.
