Fix ABI handling in libcxx/libcxxabi/llvm-libunwind.

Move ABI setup to cros-llvm eclass. Use multilib_env to set ABI env variables.
Use flags -stdlib=libstdc++ so that libcxx/libcxxabi can be installed
in a board's sysroot when libc++ is set as default in llvm.

Does not impact current llvm as libc++ is not default.

verity: Fix unit test issue with libc++

class Message in logging inherits from ostream which libc++
dislikes since ostream class has a private constructor. Inspection
showed no reason to inherit ostream. Message class only needs
to overload the "<<" operator for logging. So move the already
defined "<<" operator function inside the class.
Remove stream() function and update the macros.
