Cool, thanks!  I had to bisect to know which commit fixed it, it's this one:

    PR28459, readelf issues bogus warning

    I'd missed the fact that the .debug_rnglists dump doesn't exactly
    display the contents of the section.  Instead readelf rummages through
    .debug_info looking for DW_AT_ranges entries, then displays the
    entries in .debug_rnglists pointed at, sorted.  A simpler dump of the
    actual section contents might be more useful and robust, but it was
    likely done that way to detect overlap and holes.

    Anyway, the headers in .debug_rnglists besides the first are ignored,
    and limiting to the unit length of the first header fails if there is
    more than one unit.

            PR 28459
            * dwarf.c (display_debug_ranges): Don't constrain data to length
            in header.
