WITH_LIBCPLUSPLUS = yes makes the new libc++ being built. It can be used
with LLVM/CLANG by setting explicitely

CXXFLAGS+=              -stdlib=libc++  -std=c++11

in /etc/src.conf for being used with the base system's source build or,
if you like to compile some other software, like ports using a C++
compiler (clang++ on systems like 9.1-STABLE or c++ on 10.0-CUR where
cc/c++ refers now by default to LLVM/CLANG).

While it works well on FreeBSD 10.0-CURRENT at the moment (not for ports
at all, but for the main system's source) it might not be the same on
STABLE at the moment since the LLVM/CLANG is still 3.1 while on CURRENT
it's 3.2.
