    Do not check if CPU is RO compliant at compile time
    
    Patch d157d4246abe (Check PCIe relaxed ordering compliant) introduced run-time check
    for relaxed ordering compliance. Thus there shouldn't be any compile time checks.
    Current code is at risk on behaving differently on the same machine depending on which
    CPU it was packaged.
