I don't see that as a redundancy.  Diffutils accesses the
file system directly, as well as via gnulib.  If gnulib were
to change such that it didn't need to access the file system
(admittedly unlikely), then gnulib could drop the dependency;
but diffutils would still need it.

I expect this is why I didn't observe the bug despite testing the
buggy change with coreutils and Emacs: both invoke AC_SYS_LARGEFILE
early on.
