the C++/Qt bindings. Remove cpp and qt* from available_languages and
default_languages.
* lang/Makefile.am (DIST_SUBDIRS): Remove cpp and qt.
* lang/cpp, lang/qt: Remove.
* m4/ax_check_compile_flag.m4, m4/ax_cxx_compile_stdcxx.m4,
m4/ax_gcc_func_attribute.m4, m4/pkg.m4, m4/qt5.m4, m4/qt6.m4: Remove.
