Force GCC to always provide a C++14 flag (#29781)
* Force GCC to always provide a C++14 flag
Updated gnu logic so that the c++14 flag for g++ is always propagated.
This fixes issues with build systems that error out if passed an empty
string for a flag.
Engaging in the best kind of software engineering by updating the unit
test to pass with the value it is now passed. This should better match
the expected flag for g++ compiling with the C++14 standard
