    The name is wrong! There are zillions of ways to obtain the
    functionality. Currently we need to piggy-back definitions
    onto compiler flags.

    Compiler flags are things like "-Wall" and "-O2", that tell
    the compiler what to do. We need a name to use for definitions,
    "-Dxxx", that #define constants (dynamically at compile-time)
    in the code. Right now, -DMODULE and -D__KERNEL__ are piggybacked
    onto CFLAGS. There really should be a variable called something
    else like DEFINES and it should be exported.
