That is the case. And endian.h does not seem to define __BYTE_ORDER,
__LITTLE_ENDIAN and __BIG_ENDIAN, but BYTE_ORDER (__DARWIN_BYTE_ORDER),
LITTLE_ENDIAN (__DARWIN_LITTLE_ENDIAN) and BIG_ENDIAN
(__DARWIN_BIG_ENDIAN). I was able to get a successful build by applying
diff --git a/numpy/core/include/numpy/npy_endian.h

I confirm that the current master builds just fine.
