I don't knwo if it can help,
but if you can use ffi I think you can know the endianness of the current
platform with with this code:
ffi.cdef [[
 union endianness {
   int32_t i;
   char c[4];
local x = ffi.new('union endianness x',{i=1})
if(x.c[0]==1) then
  print "little endian"
 print "big endian"
