Long history and multiple different places where these could be set..

This is defined by endian.h (from C library).. Could be cleaner to
change that to use __BYTE_ORDER to match with the eap_peer/ikev2.c use
or move to WORDS_BIGENDIAN which is used in some more places.

Old hack..

Well, not necessarily.. This is a question of whether to use the
__BYTE_ORDER from system headers (with possible compatibility code from
common.h) or to move something specific to hostap.git (like
WORDS_BIGENDIAN). I'm not aware of places where the current
implementation would not work, but well, it could certainly be cleaned
up.
