I normally build with --disable-dependency-tracking to speed up builds,
and also build out-of-tree, and got this with the latest coreutils:

    $ cd /foo/bar/coreutils-8.23
    $ mkdir _build
    $ cd _build
    $ ../configure --disable-dependency-tracking
    checking for a BSD-compatible install... /usr/bin/install -c
    checking whether build environment is sane... yes
    [...]
    $ make
    [...]
      GEN      lib/unistr.h
      GEN      lib/unitypes.h
      GEN      lib/uniwidth.h
      GEN      lib/wchar.h
      GEN      lib/wctype.h
      GEN      src/coreutils.h
    /bin/sh: src/coreutils.ht: No such file or directory
    gmake: *** [src/coreutils.h] Error 1

Oops, all that was missing for that case was
an entry for coreutils.1 in the static dependency list.
Pity we can't use a GNU pattern rule here,
and portable suffix rules can't have prerequisites.
Note pattern rules seem widely supported, which is tempting.

Anyway I added coreutils.1 to the list and pushed.

thanks for the review,
Pádraig.
