Okay, I found the answer to this one.  The aux-files option (accessed with 
(ly:get-option 'aux-files)) indicates that these files are being created.  

It’s also occurred to me that the only way to determine the number of systems 
is to actually do the typesetting.  Any attempt, therefore, to determine the 
targets and prerequisites automatically without typesetting the document cannot 
know exactly how many there are and has to be written from that perspective.  
This part of the question was akin to asking someone how many apples are in a 
bag while keeping the bag hidden from them.
