ACT does not build on Debian 9 (GCE)

[rbotzer]

On Debian 9 (on a GCE vm-instance) I've installed the dependencies and tried make ; make -f Makesalt. I get the following error:

By comparison it builds on Ubuntu 16.04 with a warning:

$ cd act && make && make -f Makesalt

As a temporary workaround, edit the Makefile and replace '-Wall' with '-w'.

After that I ran into:

/usr/bin/ld: cannot find -lz

To fix that, install zlib1g-dev

sudo apt install zlib1g-dev

Hope this fixes it...
