There's one more interesting (surely generated) snippet in there:
------------------------------------------------------------------------
IPTABLES_MODULES = /usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug
------------------------------------------------------------------------
Makefile.in looks like this in the same place:
------------------------------------------------------------------------
IPTABLES_MODULES = @IPTABLES_MODULES@
------------------------------------------------------------------------
configure replaces this as follows:
------------------------------------------------------------------------
s!@IPTABLES_MODULES@!$IPTLIB!
------------------------------------------------------------------------
And from the build log:
------------------------------------------------------------------------
Iptables module path: /usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug (from binary)
------------------------------------------------------------------------
And indeed, the way to determine this value seems to be buggy:
------------------------------------------------------------------------
$ strings /sbin/iptables | grep '^/.*lib.*/.*tables'
/usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug
------------------------------------------------------------------------
I searched the output of "strings /sbin/iptables" for other, similar
paths, but there's just none:
------------------------------------------------------------------------
$ strings /sbin/iptables | grep 'usr'
/usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug
$ strings /sbin/iptables | grep 'lib'
/lib64/ld-linux-x86-64.so.2
libmnl.so.0
libnftnl.so.11
libxtables.so.12
libc.so.6
__libc_start_main
/usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug
$ strings /sbin/iptables | grep 'x86'
/lib64/ld-linux-x86-64.so.2
/usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug
------------------------------------------------------------------------
So the main issue here seems upstream's self-written configure script
that fails on recent iptables binaries.

I'm convinced now that lintian should emit such a warning. Retitling
and reassigning accordingly.
This tag should be very likely of severity "error".
