Where is dpkg-architecture?

I couldn't compile Pillow because the link libz.so -> libz.so.1 is missing in /lib/x86_64-linux-gnu. The Debian Policy Manual says that .so link should be installed along with the development packages. The zlib1g-dev package was installed but libz.so is missing.

root@eba34fc4c7ff:/# dpkg-query -l | grep zlib
ii  zlib1g:amd64            1:1.2.8.dfsg-5        amd64        compression library - runtime
ii  zlib1g-dev:amd64        1:1.2.8.dfsg-5        amd64        compression library - development
root@eba34fc4c7ff:/# ls /lib/x86_64-linux-gnu/libz*
/lib/x86_64-linux-gnu/libz.so.1  /lib/x86_64-linux-gnu/libz.so.1.2.8

For details see docker-library/python#305.

The real question: was removing dpkg-dev and dpkg-architecture intentional? It was there, but now it isn't.

This is not an issue in the Debian image. To my knowledge it has never included dpkg-dev. See my comment in related python issue.
