Don't generate constructor wrappers if a base class has a private constructor

g++-5 errors out with this now with errors such as:

default_constructor_wrap.cxx:665:27: error: use of deleted function ‘FFF::FFF()’
   result = (FFF *)new FFF();
                           ^
default_constructor_wrap.cxx:314:7: note: ‘FFF::FFF()’ is implicitly deleted because the default definition would be ill-formed:
 class FFF : public F {
       ^
default_constructor_wrap.cxx:301:4: error: ‘F::~F()’ is private
    ~F() { }
    ^
default_constructor_wrap.cxx:314:7: error: within this context

===========================
2015-07-07: wsfulton
SWIG no longer generates a wrapper for a class' constructor if that class has
any base class with a private destructor. This is because your compiler should
not allow a class to be instantiated if a base has a private destructor. Some
compilers do, so if you need the old behaviour, use the "notabstract" feature, eg:
%feature("notabstract") Derived;
class Base {
~Base() {}
};
struct Derived : Base {};
