3.3.4 Exercise: Directing makefile to Re-Create the dprime.h File

Add a target that instructs dtrace to re-create the dprime.h file in the event that changes are subsequently made to the dprime.d file. This step ensures that you do not have to manually run the dtrace -h -s dprime.d command if any changes are made.

This exercise also has you direct dtrace to create a prime.o file.
