Yeah. Include handling changed in the misgenerated configure, but the
hunk that broke it was (tabs smushed to spaces, sorry):

-      as_dir=$dirpart/$fdir; as_fn_mkdir_p
-      # echo "creating $dirpart/$file"
-      echo '# dummy' > "$dirpart/$file"
-    done
+    { echo "$as_me:$LINENO: cd "$am_dirpart" \
+      && sed -e '/# am--include-marker/d' "$am_filepart" \
+        | $MAKE -f - am--depfiles" >&5
+   (cd "$am_dirpart" \
+      && sed -e '/# am--include-marker/d' "$am_filepart" \
+        | $MAKE -f - am--depfiles) >&5 2>&5
+   ac_status=$?
+   echo "$as_me:$LINENO: \$? = $ac_status" >&5
+   (exit $ac_status); } || am_rc=$?

The old implementation only needed mkdir: the new one related on make
am--depfiles working, but that's an Automake 1.16 feature, so the make
invocation failed and we never got any $DEPDIRS out of it.
