Dovecot LTO build failure

[Arjen de Korte]

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?
