Source: dovecot
Version: 1:2.2.33.2-1
Tags: patch
User: helm...@debian.org
Usertags: rebootstrap

dovecot fails to cross build from source, because it configures for the
build architecture by not passing any --host to ./configure. Deferring
that task to dh_auto_configure is an easy solution. After doing so,
dovecot cross builds successfully provided one sets a significant pile
of autoconf cache variables for AC_RUN_IFELSE checks. Please consider
applying the attached patch.
