I don't believe that is 100% correct. In fact, if I remember correctly, it wasn't too long ago a Turkish developer filed a proposal with the FAA for a tower of 1,080'. However, I believe that proposal has died - but, not due to any FAA regulation. And, Houston already has 2 supertalls.
The FAA doesn't directly restrict the height of buildings, but issues a "determination of hazard" when buildings are too tall near airports. At that point, local zoning boards are reluctant to approve construction and buildings can become unaffordable because of higher insurance costs and smaller size.
If I'm not mistaken - as-the-crow-flies distances from a downtown to nearest edge of a runway (using Google Earth):
Dallas - DAL = 4.4 miles
Austin - AUS = 5.4 miles
Houston - HOU = 8.6 miles
Dallas - DFW = 13.8 miles
Houston - IAH = 14.1 miles
