Don't know about Raphael, but I certainly can do that now.

That code resides in a /usr/lib/live/build/binary_iso script, that one 
gets after installing Kali's 'live-build' package (which of course is 
the parent package one needs to run the scripts we've seen in 
'live-build-config'). I've uploaded a copy of that script at [1] 
(altered to show the full xorriso command line).

And after letting a build process to run overnight, I can also provide a 
full log of the xorriso pass, with the options being used, attached.

Looks like your suspicion is correct: they are using --hardlinks with 
mkisofs. And of course, I confirmed that the ISO I got had the same 
issue as the official Kali ones.

Now, I still fail to see what information is so private about this kind 
of commandline (and other xorriso invocations) that should preclude it 
from being stored on the ISO, and thus avoid a lot of time wasted on 
this exercise. But I guess that's just me:

xorriso -as mkisofs -R -r -J -joliet-long -l -cache-inodes -iso-level 3 
-isohybrid-mbr /usr/lib/ISOLINUX/isohdpfx.bin -partition_offset 16 -A
