Sounds fine. I suggest simplifying the overall problem by having
the generated dependency file contain a simple list of files. This
list can be easily formed into any convenient form using simple
scripts or make rules. This side-steps the whole issue of what to
put to the left of the :.

At first blush one might guess that this whole thing can be done
within iverilog and ivlpp, but then modules brought in by the -y
flag will get missed. So you might choose to eventually continue
the support into the ivl core.

So, iverilog (the driver) will create the file, then ivlpp and
ivl append file names to it, one per line.
