It's not a special make variable, so far as I can find in the gmake manual.

It looks like the idea was to list filename patterns that could be subject
to automatic removal during "make clean", but Peter backed off listing it
in the clean target and then forgot to remove the variable.

I couldn't find any contemporaneous discussion in the archives, but I do
vaguely recall that at some point --- maybe not just then --- we talked
about having such auto removal and decided it was a bad idea.  Editor
backup filenames, for instance, vary depending on your weapon of choice;
and core file names vary too, these days.  So there's a project policy
that we wouldn't enable any such removal by the makefiles.  (These days
people would probably turn to git commands for such cleanup, anyway.)

In short, yeah, I think we could nuke that.  But maybe Peter remembers
it differently.
