[bug-gettext] autopoint and m4_ifndef

[Sami Kerola]

Hello,

My archlinux got gettext update to version 0.18.3 which made
util-linux compilation to break. The util-linux fails at ./autogen.sh
at line 'autopoint --force' which finds the following, and m4_fatal
failure occurs.

m4_ifndef([PKG_PROG_PKG_CONFIG],
  [m4_fatal([Could not locate the pkg-config autoconf
    macros. These are usually located in /usr/share/aclocal/pkg.m4.
    If your macros are in a different location, try setting the
    environment variable AL_OPTS="-I/other/macro/dir" before running
    ./autogen.sh or autoreconf again.])])

The version 0.18.2 found PKG_PROG_PKG_CONFIG. So I build the latest
gettext version from git it had same issue. After running git bisect
for it seems the following gettext commit caused something unexpected
to go wrong.

    autopoint: extract macro directories from configure.ac

Or perhaps I did something silly. Can you cannot reproduce the error
with recent gettext?

git clone git://git.kernel.org/pub/scm/utils/util-linux/util-linux.git
cd util-linux && ./autogen.sh
