Deadlifts will definitely target the glutes, squats I would say that it depends on your form. A wider stance, placing the bar lower, and trying to "spread the floor" as they say in powerlifting cirlces will no doubt increase the glute involvement in a squat. So to minimize it, place the bar high, use a medium to narrow foot stance and work on "pressing through the floor" and or keeping more upright--also work on keeping your arms perpendicular to the floor (rather than flair back).
On a side note, I think most women are way too obsessed with their butts, I know you may think it's big, but I'm sure most guys wouldn't think so. And a further side note, unless you are a quite muscular woman I doubt switching exercises will make much a difference in your glute measurements--it could make it look slightly different (perhaps not stick out quite as much)--but if you really want to make a difference in the tape measure losing some body far will mostlikely lead to greater results. Best of luck, hope I didn't confuse the issue any farther:P
