 There are two cases here.

  1. GCC and Clang define `__ARMEL__` on little-endian ARM and `__ARMEB__`
 on big-endian ARM, so if either is defined, use it.
  1. Visual C++ for WinCE target (not sure about ARM version of Win8 yet)
 however does not define absolutely anything specific. It defines `__ARM__`
 and `ARM`, but that might be defined in other compilers on big-endian too
 and `_M_ARM` one would expect in analogy to `_M_X64` and similar is
 '''not''' defined. However there are no big-endian Windows API
 implementations at all, so the attached patch simply defaults to little-
 endian if `_WIN32` is defined.

 Note: The attached patch is minimal to get things to work, but the various
 `_M_*` defines can probably be excluded from the condition if they get
 covered by `_WIN32`.
