Trying to build Dovecot 2.2.34 on OpenBSD fails.
This seems to have been introduced by this commit.. https://github.com/dovecot/core/commit/4a9020ed888caf03fd3132a30a7818b01daa4...
This is libtool-related. GNU libtool prints a warning but is able to link:

But it fails with OpenBSD libtool:

Clearly OpenBSD libtool isn't handling something that GNU libtool can cope with, but given the warning from GNU libtool it doesn't seem entirely legit in the first place.
