Remove make_unique ambiguity when using gcc 4.9 in C++14 mode.
gcc 4.9.4 has __cplusplus at 201300L instead of 201402L when in C++14 mode, I guess indicating incomplete support. Anyways, it causes a problem with this check as in c++14 mode in old gcc we were defining absl::make_unique when std::make_unique was present
