# TestBigEndian
# -------------
#
# The TestBigEndian.cmake module that ships with CMake, which
# checks if the system is big endian or little endian, assumes
# that a binary is produced that will have bytes that correspond to the
# endianness on the target system. Since emscripten produces Javascript, we
# override the default behavior and always return little endian.
