Using CNOP to achieve alignments greater than doubleword requires
an appropriate SECTALGN option. Unfortunately, we don't have any
quad-length or quad-aligning adcons, so that JD and QD align to
doubleword boundaries and are 8 bytes long. XD items (external
dummy sections) also require SECTALGN(16) if the DXD item requires
quad alignment.

Why do you need this alignment and for what? I ask these questions
because this issue is complicated. CNOP supports quadword alignment,
and it can sometimes be used to do what one wants to do. Or again, QD
and JD both specify quadword alignment implicitly. [But take care: xD
certainly does not always do so.]
