I was taught, assuming the runway length was sufficient, to not use full flap when there was a significant crosswind. This technique has worked well for me as the airports I use typically have long runways for the type I fly, so use half flap in these conditions.
The main thing to bear in mind is that the landing roll will be longer - and human factors being what they are you can end up focussing on the crosswind and how best to deal with it and overlook runway length / the fact that the aircraft will float longer if not using usual landing flaps.
