   2    in question.  See string/endian.h for how to define it.

   4    If only the stub bits/endian.h applies to a particular configuration,
   5    bytesex.h is generated by running a program on the host machine.
   6    So if cross-compiling to a machine with a different byte order,
   7    the bits/endian.h file for that machine must exist.  */
