+/** @file
+  Provide an empty lib instance constructor for modules that can only run from
+  RAM but are not DXE_RUNTIME_DRIVER modules.
+
+  This ensures that e.g. any HobLib constructor is ordered correctly. (The
+  DXE_CORE calls constructors late, but the DXE_CORE HobLib instance needs no
+  construction anyway.)
