[Buildroot] [PATCH] automake: bump version to 1.15

[Vicente Olivert Riera <Vincent.Riera@imgtec.com>]

Hi Thomas, Gustavo,

First issue found with automake-1.15. The package libmemcached fails at
the configure phase with the following error:

configure: error: cannot find install-sh, install.sh, or shtool in "."
"./.." "./../.."

It works fine using the automake version we have right now in Buildroot.

This snippet is included in the configure script if we use
automake-1.15, and it fails because is trying to find some files which
don't exist in the "." "./.." "./../.." directories:

-----------------------------------------------------
ac_aux_dir=
for ac_dir in "$srcdir" "$srcdir/.." "$srcdir/../.."; do
  if test -f "$ac_dir/install-sh"; then
    ac_aux_dir=$ac_dir
    ac_install_sh="$ac_aux_dir/install-sh -c"
    break
  elif test -f "$ac_dir/install.sh"; then
    ac_aux_dir=$ac_dir
    ac_install_sh="$ac_aux_dir/install.sh -c"
    break
  elif test -f "$ac_dir/shtool"; then
    ac_aux_dir=$ac_dir
    ac_install_sh="$ac_aux_dir/shtool install -c"
    break
  fi
done
if test -z "$ac_aux_dir"; then
  as_fn_error $? "cannot find install-sh, install.sh, or shtool in
\"$srcdir\" \"$srcdir/..\" \"$srcdir/../..\"" "$LINENO" 5
fi

# These three variables are undocumented and unsupported,
# and are intended to be withdrawn in a future Autoconf release.
# They can cause serious problems if a builder's source tree is in a
directory
# whose full name contains unusual characters.
ac_config_guess="$SHELL $ac_aux_dir/config.guess"  # Please don't use
this var.
ac_config_sub="$SHELL $ac_aux_dir/config.sub"  # Please don't use this var.
ac_configure="$SHELL $ac_aux_dir/configure"  # Please don't use this var.
-----------------------------------------------------

That snippet is NOT included if we don't use automake-1.15.
