[SSSD] [PATCH] build: call AC_BUILD_AUX_DIR before anything else

[Jan Engelhardt]

sssd's configure.ac (abridged) contains these lines:

	AC_INIT([sssd], ...)
	m4_ifdef([AC_USE_SYSTEM_EXTENSIONS],
		[AC_USE_SYSTEM_EXTENSIONS], [AC_GNU_SOURCE])
	AC_CONFIG_AUX_DIR([build])

When turned into configure, this will be emitted:

	ac_aux_dir=
	for ac_dir in build "$srcdir"/build; do
	  if test -f "$ac_dir/install-sh"; then
	    ac_aux_dir=$ac_dir
	    ac_install_sh="$ac_aux_dir/install-sh -c"
	    break

However, with automake commit v1.14.1-36-g7bc5927, this will be emitted
instead:

	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

As configure no longer looks into build/ for install-sh, running
./configure fails:

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

I think the error is that someone placed AC_BUILD_AUX_DIR
too late. Move it upwards.
