bootstrapping coreutils: autopoint from gettext 0.18.3.1 fails

[CCing coreutils]

Since
  http://git.sv.gnu.org/cgit/gettext.git/commit/?id=32e194b4dc
  https://lists.gnu.org/archive/html/bug-gettext/2013-07/msg00002.html
bootstrapping coreutils fails during the autopoint run:

  ./bootstrap: autopoint --force
  sh: build-aux/git-version-gen: No such file or directory
  /usr/bin/m4:configure.ac:444: cannot open `m4/cu-progs.m4': \
    No such file or directory
  autom4te: /usr/bin/m4 failed with exit status: 1
  autopoint: *** Missing version: please specify in configure.ac \
    through a line 'AM_GNU_GETTEXT_VERSION(x.yy.zz)' the gettext \
    version the package is using
  autopoint: *** Stop.

So m4 seems to be used earlier in the process,
to parse the AN_GNU_GETTEXT_VERSION from configure.ac,
before we have things setup for m4.

Bug
  http://savannah.gnu.org/bugs/?40083
seems to be related, but the fix was to just discard stderr.

Any idea?

Thanks & have a nice day,
