There isn't, no.  (and?)

Because DESTDIR is the name of a make variable, which is employed in
the sentence which failed in my original bug report (file
"nt/Makefile.in", target "install"):
  $(INSTALL_DATA) README.W32 "$(DESTDIR)${datadir}/emacs/$(version)"

When I try to show the value of that variable, at that point, it seems
to be empty (which seems like a bug).

No, I didn't.  Sorry if I said something that confused you, but AFAIK,
I don't have to set that variable anywere.

When I checked, I think it existed, but I'm going crazy with so many tests...

I'd suggest you to try to reproduce this yourself.  But failing that,
I'll do it later today...
