Philippe Teuwen 2c4eda6ab9 Fix 2 issues in proxendian.h, see details:
Only some OSes include endian.h from sys/types.h, not Termux, so let's include endian.h directly.
Moreover the past logic defined BYTE_ORDER to an undef macro, so BYTE_ORDER was not undef but def to 0
and BYTE_ORDER != LITTLE_ENDIAN && BYTE_ORDER != BIG_ENDIAN was always false as (0!=0 && 0!=0)
