A bit pedantic, sorry, but it's more accurate to say that, on both big
and little endian n64, what generic ELF64 calls r_info is instead a
32-bit symbol index (r_sym) followed by 4 byte fields (r_ssym, r_type3,
r_type2, r_type).  It's just that the code is choosing to represent all
5 fields as a single 64-bit integer.
