    C++ feature checks: Filter out libstdc++ sprintf warnings
    
    On OpenBSD linking to `libstdc++` with GCC 6.4 always warns:
    
        warning: sprintf() is often misused, please use snprintf()
    
    These do not affect the availability of C++ features we're checking,
    so filter them out.
    
    Fixes: #18602
