[PATCH] scripts: add autotools-install, for those stuck with outdated tools

[Jim Meyering]

FYI, this adds the autotools-install script, formerly at:

    http://people.redhat.com/meyering/autotools-install

As the commit log says, it is a:

    New script, so you can always build
    from git-cloned sources, even when they require bleeding edge
    m4, autoconf, automake, etc.

+# Building coreutils from a git-cloned directory may require versions of
+# tools like autoconf, automake, gettext, etc. that are newer than the ones
+# provided by the distribution on which you want to build.  In that case,
+# you can use this script to bootstrap the "autotools" tool chain, starting
+# with m4 (prereq of autoconf), then autoconf, which a prereq of automake,
+# etc.  It also builds a few others, including gettext and pkg-config.
+# The results are installed in a directory whose --prefix you specify, and
+# it tells you how to update envvars like PATH and (if you use pkg-config)
+# PKG_CONFIG_PATH.
