The binding defaults to little endian and (in implmentation terms)
always has done though that used to be unintentional.  There *are* a
reasonable number of devices out there which are native endian, for
example most of the MIPS chips switch the endianness of the entire chip
rather than just the CPU, but most of the current usage has been on ARM
devices which only switch the core.
