The timestamps look OK to me:

Perhaps the cause is this rule, though:
dblocation.texi: ../locate/dblocation.texi
cp ../locate/dblocation.texi $@
This will clearly update the mtime of dblocation.texi.
However, this rule is intended as a workaround for what would
otherwise be a failure in "make dvi". The texi file is changed:
$ git diff doc/find.texi | cat
diff --git a/doc/find.texi b/doc/find.texi
index 7aa20e5..fe0b2ce 100644
--- a/doc/find.texi

-@include ../locate/dblocation.texi
+@include dblocation.texi

However, the old version of this code no longer works with the
combination of TeX and texinfo I have installed. Reverting the
change, rebuilding the makefiles (i.e. re-running gnulib-tool etc.)
and doing make dist again we see the failure that I made the above
change to evade:

I suspect the problem here is the texio2dvi argument
--build-dir=find.t2d - in other words, the generated makefile now uses
texi2dvi in "tidy" mode, and that changes the current directory of the
TeX formatter; it can no longer find ../locate/dblocation.texi.
Certainly strace shows that the program tries to open the file using
exactly " ../locate/dblocation.texi" and cannot because that's not any
longer the correct relative path to the input (though it is the
correct relative path to the input if the working directory were the
same directory as contains find.texi).
It looks to me as if the relevant change was introduced by Stefano
Lattarini in commit 205c7572497789676bea3167b9cdeede69236a16.
