In Preview 11, when referencing a MonoDroid class library in a MonoDroid
application, the build process will throw a NullReferenceException:

monodroid : error 1: System.NullReferenceException: Object reference not set to
an instance of an object.

     at Monodroid.Droidinator.CreateApk()
     at Monodroid.MainClass.Main(String[] argv)

After editing the MonoDroid application's project properties and changing the
Linking property from the default "Sdk and User Assemblies" to "Sdk Assemblies
Only", the problem goes away.

Reproducible: Always

Steps to Reproduce:
1. Create a MonoDroid application.
2. Create a MonoDroid class library.
3. Reference the class library project in the application.
4. Try to build.
Actual Results:  
Build failed, NullReferenceException was thrown by monodroid.exe.

Expected Results:  
Build succeeds.
