Build the split-select tool without C++11 support

It was complicated to get the tool building on Windows, Linux,
and OSX with C++11 support.

OSX uses Clang to build C++11 binaries, which requires the libc++
standard library. Since most of the dependencies of this program
are built against libstdc++, this was difficult to resolve.

Now we build without C++11 support.
