Some macros, structures definitions, ... depends on the
endianness. This is generaly done via some header file
but these headers need information from the compiler via
the macros __BYTE_ORDER__, itself being defined to
__ORDER_BIG_ENDIAN__ or __ORDER_LITTLE_ENDIAN__.
Let sparse predefine these macros like compilers do.
