As fpc/Lazarus dos not (yet) provide run time packages, and IMHO it will 
ask for major problems when compiling the Lazarus IDE to contain the 
Dongle code, I suppose your best option is to replace the Dongle .OBJ 
file by a small pascal function and use this to build your package to 
allow it for compiling the IDE (providing the design time stuff) and the 
user program (providing the run time stuff).

Now you need to "fake" the runtime package behavior by doing the said 
small pascal function in a way that it dynamically (not in the startup 
code !) loads and then uses a dll .

The dll would be done in a way that it just forwards the call to the 
functions provided by Dongle .OBJ to same, and statically links to it.
