That used to be a serious problem. Now they seem to be selling ATB's with extra long steering tubes with spacers to allow customizing. I started building/assembling our own bikes so I could cut the steering tube where we wanted them. If not sure, I leave a half inch or more protruding above the stem. And then there are always riser bars which can be cut in length to the that of the flat bars.
