Subject: MIPS assembly pack: default heuristic detection to little-endian.

MIPS assembly pack: default heuristic detection to little-endian.

Current endianness detection is somewhat opportunistic and can fail
in cross-compile scenario. Since we are more likely to cross-compile
for little-endian now, adjust the default accordingly.
