Well, not really.  libtoolize has

    if test -n "$ac_auxdir"; then
      # If $configure_ac contains AC_CONFIG_AUX_DIR, check that it was
      # not given in terms of a shell variable!
[...]
    else
      # Try to discover auxdir the same way it is discovered by configure.
      # Note that we default to the current directory.
      for dir in . .. ../..; do
        if test -f "$dir/install-sh"; then
[...]

and the configure behavior mentioned in that comment is documented in
'info Autoconf Input'.

Question is, whether the libtoolize behavior is desirable, and if so,
then we should document it, and if not, we should change the code.

That is undesirable, but ought to be work-aroundable easily by using
AC_CONFIG_AUX_DIR in configure.ac.
