You need

   Library_Type : Build_Kind := external ("LIBRARY_TYPE", "static");

which means that if you don't have LIBRARY_TYPE defined (either in the
environment, or via the gprbuild flag -XLIBRARY_TYPE=relocatable) it'll
default to "static".

I don't know how using your first version (without the default) and
without having LIBRARY_TYPE defined could ever have worked, this has
been as it is now for a long time.
