Thank you for trying to test this issue. I agree that this should not be
an issue on NetBSD 10.0 [1], even though ldconfig is still available for
use. For OpenBSD, version 7.6 has been added to the CI [2], and it
exhibits the same behaviour as version 7.5. Until the finish_cmds for
OpenBSD are removed or updated sufficiently, the --reorder-cache [3] and
--no-finish [4] commands should be useful for development and testing of
shared libraries for these unusual / complex cases that libtool's 'Use
local version' test demonstrates.
