Tensorflow micro lite compatibility

@nseidle these are some changes that I had to make when getting the TFLM code to run on Edge. My concern is about the 2nd commit. Maybe one solution would be to implement a template function that could be used wherever the original macro would have been used. That way the signatures can be different (conflict is with min as used here):

stl_algobase.h

  template<typename _Tp, typename _Compare>
    _GLIBCXX14_CONSTEXPR
    inline const _Tp&
    min(const _Tp& __a, const _Tp& __b, _Compare __comp)
    {
      //return __comp(__b, __a) ? __b : __a;
      if (__comp(__b, __a))
	return __b;
      return __a;
    }

Here's a tidbit: http://www.suodenjoki.dk/us/archive/2010/min-max.htm

I like the adc setup fix.

I think the #ifdef undef fix is fine. If min/max functions are wrong because of our overwriting, the user has bigger problems.
