Then why not simply 
rm debian/copyright_newhints
in the clean target?

The problem is that for the moment, the message is misleading: a message
indicating "Fully compare debian/copyright_hints with
debian/copyright_newhints and replace debian/copyright_hints with
debian/copyright_newhints"  is displayed, and the copyright_newhints
file does not exist. I first had to search for it in other directories,
run the licensecheck from sources (hence #625442) to make sure it
worked, and finally had to look at the utils.mk source to figure out
that the indicated file was indeed removed just after the message is
