I would like to know what purpose a constructor for an abstract class serves; as we do not instantiate abstract classes, why would we ever need such a constructor?

there will be times when you have some common initialization of instance variables that all the inheriting classes need to set up. You do instantiate an abstract class when you extend it and that concrete class has a constructor that will either supply the parameters to the constructor of the abstract class.
