Pulled latest versions of config.guess and config.sub from their upstream locations (as documented in those files). This is necessary for the configure process to correctly recognize GNU/Linux on AAarch64, for example.
Add the %newobject SWIG declaration to the factory methods createLattice() and createTagger() of the class MeCab::Model. This makes it clear that the caller takes on ownership of the pointer returned by these factory methods. Without this declaration, calls in e.g. Java to Model.createLattice() and Model.createTagger() will leak memory, as the generatedd Java Lattice and Tagger proxy classes do not know that they have ownership of the underlying C++ pointers. As a result, instances of the proxy classes fail to delete the underlying C++ objects, leading to native (off-JVM-heap) memory leaks that are difficult to debug.
Update of auto-generated code only; no manual changes. Reran "make" in directory mecab/swig, using current SWIG version 4.0.2.
