When plain cpp check fails, cpp.req tries to process the same file in c++ mode, which requires c++ support to be installed. As result, when c++ support is not installed, cpp.req clutter the log with vain attempts to process files in c++ mode. This change reduces the noise by checking whether c++ support is actually available.
