When using stdlib (default on Linux) and compiling with "-std=c++14", errors
like the following occurr. Avoid them by not requiring c++14.
$ clang --version
Ubuntu clang version 3.6.0-2ubuntu1~trusty1 (tags/RELEASE_360/final) (based on LLVM 3.6.0)
Target: x86_64-pc-linux-gnu
Thread model: posix
$ cat clangtest.cpp
#include <random>
$ clang -std=c++11 -fsyntax-only clangtest.cpp # Fine with c++11/stdlibc++
$ clang -std=c++14 -fsyntax-only clangtest.cpp # Ops with c++14/stdlibc++
