Can you try the patch below? Originally meant for [1], but, user doesn't
have the original setup anymore[2] so I couldn't get it tested (no ARM HW
of my own).

[1] https://mail-index.netbsd.org/pkgsrc-users/2023/12/04/msg038541.html
[2] https://www.unitedbsd.com/d/1207-trying-to-build-exiv2-0820nb3-on-aarch64

Note that the comment in mk/scripts/larger_symbol_version.awk is misleading
as well. It does not return 1 if the supplied version is larger: it always
returns 0 and you have to parse its stdout to make any determination.
