Details:

I think it's time to start enabling Octave's build to use C++11 if possible
(or C++0x). There is an autoconf-archive macro that we can use for this
purpose.

I'm not advocating for using C++11 features everywhere, but at least enable
the compiler options to make it possible to start using some library features
if possible.

There are some math functions that are available in the C++ standard library
in C++11. Newer versions of LLVM also require building with C++11 (they've
apparently started using the auto keyword and std::move() everywhere in their
inline functions).

Not for 4.0 obviously.
