// This pretty simple file checks if the system is LITTLE_ENDIAN or BIG_ENDIAN
// it does that by putting a 1 and a 0 in an array, and read it out as one
// number. If it is 1, it is LITTLE_ENDIAN, if it is 256, it is BIG_ENDIAN
//
// After that it outputs the contents of an include files (endian.h)
// that says or TTD_LITTLE_ENDIAN, or TTD_BIG_ENDIAN. Makefile takes
// care of the real writing to the file.
