Out of curiosity tried to build dh-linktree on a stretch for stretch.
Here are the steps:

Install cowbuilder and create stretch chroot:

export DISTR=stretch;cowbuilder --create --architecture amd64
--distribution ${DISTR} --basepath
/var/cache/pbuilder/base-${DISTR}-amd64.cow

mkdir pkg; cd pkg

dget -x
http://http.debian.net/debian/pool/main/d/dh-linktree/dh-linktree_0.6.dsc

export DISTR=stretch;cowbuilder build dh-linktree_0.6.dsc --architecture
amd64 --distribution ${DISTR} --basepath
/var/cache/pbuilder/base-${DISTR}-amd64.cow


  pbuilder-satisfydepends-dummy : Depends: debhelper (>= 11) but it is
not going to be installed
  Unable to resolve dependencies!  Giving up...

Ok, doesn't work.

Let's add backports to our chroot

echo 'HOOKDIR="/var/cache/pbuilder/hook.d/"' >> /etc/pbuilderrc

mkdir /var/cache/pbuilder/hook.d/

cp /usr/share/doc/pbuilder/examples/D20addnonfree
/var/cache/pbuilder/hook.d/D20addbackports

perl -pi -e 's/sid\scontrib\snon-free/stretch-backports main/'
/var/cache/pbuilder/hook.d/D20addbackports

cat /var/cache/pbuilder/hook.d/D20addbackports
#!/bin/bash
# example file to be used with --hookdir
#
# add non-free and contrib distributions to
# /etc/apt/sources.list

echo ' Add sid non-free mirror to distribution'
echo 'deb '$(awk '/^deb / {print $2} ' < /etc/apt/sources.list | head -1
)' stretch-backports main' >> /etc/apt/sources.list
apt-get update


export DISTR=stretch;cowbuilder build dh-linktree_0.6.dsc --architecture
amd64 --distribution ${DISTR} --basepath
/var/cache/pbuilder/base-${DISTR}-amd64.cow

Seem to work
