Bug#1051431: libauthen-pam-perl FTCBFS: invokes ./configure without --host

[Helmut Grohne]

Source: libauthen-pam-perl
Version: 0.16-5
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

libauthen-pam-perl fails to cross build from source, because ./configure
is run without --host and fails that way. It is run from Makefile.PL
without any arguments and this makes injecting the --host flag
particularly difficult. I propose making that configure invocation from
Makefile.PL optional. If it sees a config.status, it may assume that
configure was successful and skip it. In the packaging, we can then
simply configure before handing off to Makefile.PL and let
dh_auto_configure pass the right flag. I'm attaching a patch for your
convenience. Does that work for you?
