"-Werror=format-security" compilation option complains about the way
    we used some of the standard function (like snprintf) 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 upstream code.
