scikit-image/scikit-image issue 4369
We unconditionally add ``-std-c99`` to the gcc compiler in order
to support c99 with very old gcc compilers. However the same call
is used to get the flags for the c++ compiler, just with a kwarg.
Make sure in this case, where it would not be legal, the option is **not** added
