Bug#929420: libsieve FTCBFS: does not pass --host to ./configure

[Helmut Grohne <helmut@subdivi.de>]

Source: libsieve
Version: 2.2.6-2
Tags: patch
User: helmutg@debian.org
Usertags: rebootstrap

libsieve fails to cross build from source, because it does not pass
--host to ./configure. The easiest way of fixing that - using
dh_auto_configure - makes libsieve cross buildable. Please consider
applying the attached patch.
