Using the reproducer bisected to:

I can also confirm that reverting it on top of 2.40 makes things work again
(assuming I resolved the conflicts correctly) .

    Only use wild_sort_fast

    there's no reason why the tree-based variant can't always be used
    when sorting is required, it merely needs to also support filename
    sorting and have a fast path for insertion at end (aka rightmost tree
    leaf).

    The filename sorting isn't tested anywhere and the only scripttempl
    that uses it is avr (for 'SORT(*)(.ctors)'), and I believe even there it
    was a mistake.  Either way, this adds a testcase for filename sorting as
    well.

    Then the non-BST based sorting can be simplified to only support
    the fast case of no sorting required at all (at the same time renaming
    the two variants to _sort and _nosort).
