It's a fairly good assumption that if someone sets ACLOCAL_FLAGS, then
they will set it correctly. Following is the code snippet from 
GTK+'s autogen.sh that checks the no-ACLOCAL_FLAGS case.

I've Cc'ed Shawn Amundson who wrote the test, but I think it should
be fine to steal in any case ... it's not doing anything 


if test -z "$ACLOCAL_FLAGS"; then
        acdir=`$ACLOCAL --print-ac-dir`
        m4list="glib-2.0.m4 glib-gettext.m4"
        for file in $m4list
                if [ ! -f "$acdir/$file" ]; then
                        echo "WARNING: aclocal's directory is $acdir,
                        echo "         no file $acdir/$file"
                        echo "         You may see fatal macro warnings
                        echo "         If these files are installed in
/some/dir, set the ACLOCAL_FLAGS "
                        echo "         environment variable to \"-I
/some/dir\", or install"
                        echo "         $acdir/$file."
                        echo ""
