In openSUSE Tumbleweed (and several other distributions as well),
packages are build by default with linktime optimization (LTO)
enabled. This didn?t work for Dovecot, so until now LTO was disabled
for Dovecot. There is a way to make it work though, see the following
link:

So far a fix has not made it to upstream, the latest version 2.3.30
still fails to build without this patch. Is there any news to report
regarding this?
