Zamir found this issue with the Documentation man pages:

Note, I'm not sure the proper way to fix this. I think this is the last
issue I need to resolve before making the tag.

Hi Zamir,

Thanks a lot for looking into this. I took your advice and reverted my
blind copy of the Makefiles, scripts and include headers, and instead
copied over their full history from the Linux kernel Tools directory.

You can see that update no (which now includes the utilities.mak as well).

Can you see if this patch fixes your current issue?
