I think the  easiest solution is simply to have a  big endian and little
endian reference values. Otherwise we'll  have to swap data according to
its type (using hton like functions)  as some tests do use uint8_t data,
others int16_t and so on, sometimes it's even a mix of both (uint8_t for
ref1/2 and int16_t for current)

As the  Makefile uses  the configure values,  you can define  Big endian
crc32 references enclosing them with:
