Your best bet is to read byte per byte and reassemble words yourself:

let input_int2_le ic =
  let b1 = input_byte ic in
  let b2 = input_byte ic in
  b1 lor (b2 lsl 8)

let input_int2_be ic =
  let b1 = input_byte ic in
  let b2 = input_byte ic in
  (b1 lsl 8) lor b2

and similarly for 4-byte integers.
