"-Werror=format-security" compilation option complains about the way
    we used some of the standard function (like snprintf) usage in our code.
    Hence modified spec file to build binary without "-Werror=format-security"
    option.
    
    Note that this is the temporary workaround to build packages. We should
    fix real issue in our code.
