openrisc: pass endianness info to sparse
openrisc is big-endian only but sparse assumes the same endianness as the building machine. This is problematic for code which expect __BYTE_ORDER__ being correctly predefined by the compiler which sparse can then pre-process differently from what gcc would, depending on the building machine endianness. Fix this by letting sparse know about the architecture endianness.
