Potential contribution: obj ordering for `libtool` < 2.2.7b

While investigating a .a archive reproducibility issue, we found that libtool prior to 74c8993c (first included in version 2.2.7b) did not sort find output. It seems that many packages (including all released gcc versions so far) are bootstrapped with a libtool < 2.2.7b, so I'm wondering if perhaps this is a good candidate for inclusion in the documentation?
