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:
#ifdef ARCH_IS_BIG_ENDIAN
...
#else
...
#endif
