Subject: [PATCH] Use c++ 11 for MySQL 5.7 to fix build in mac (#56384)

https://github.com/NixOS/nixpkgs/issues/49174 shows us the error that we were experiencing.
The last successful build was https://hydra.nixos.org/build/81938220, with the first failing here: https://hydra.nixos.org/build/82083071

The difference between these 2 builds seems to be Protobuf 3.4 being updated to Protobuf 3.6.
Protobuf fails because the newer version uses newer C++ features.

This commit makes MySQL 5.7 use C++ 11 to fix these issues.
