Build C++ based packages using C++11

[Michael Gmelin]

Hi,

Now that most ports build ok with clang, are there any steps planned
towards supporting C++11 and libc++ in the ports tree? I'm thinking of
flags like NEEDS_CPP98, NEEDS_CPP11 etc. With C++14 at the horizon I
expect more problems with ports depending on C++11 and even though
mixing standard libraries and language revisions might build in many
cases, it can lead to terrible problems at run time.
