According to what Yury told me on IRC, it's a cross-compilation issue. He wrote me that the following commands returns b'C?\xff\x01\x02\x03\x04\x05' which is the double big endian version, but DOUBLE_IS_BIG_ENDIAN_IEEE754 is not defined from pyconfig.h

./python  -c 'import struct; print(ascii(struct.pack("d", 9006104071832581.0)))'
