ENH: Test Fortran and C++ in one executable 

This extends the Fortran-to-C interface test to add a C++ source file.
The executable can only link with the C++ linker and with the proper
Fortran runtime libraries.  These libraries should be detected by CMake
automatically, so this tests verifies the detection functionality.
