aarch64: Add minimal C++ support

The patch resolves compilation issues for the C++ language. Previous
patch series contributed to C++ as well, however, C++ could not be
tested until we got a C++ compiler and could build at least a "Hello
World" C++ program, and in reality, more than that.

Another issue has been fixed in the libstdc++ patch.
