In the next patch we'll add a simple query function to the XenHypercallLib library class that is supposed to be called by initialization code in modules. Among those, in constructors of dependent libraries too.
Library construction ordering is ensured only between libraries with constructors, plus we shouldn't allow a dependent library with a constructor to call into ArmXenHypercallLib (the simple query function) before ArmXenHypercallLib is constructed itself. For this reason, introduce an empty constructor.
