Fixes the following issue:

utACK. Can't hurt. But i guess installing automake will install autoconf (as depends)?

Ah, good point (for both Ubuntu and Debian). Fixed (rebased).

Isn't it the other way around - doesn't autoconf install automake as dependency?

I've installed bitcoin core on many VMs (both Debian and Ubuntu) from scratch by following just the build-unix.md instructions, I'm not convinced that this change is needed.

No. You are confusing their relationship. From https://www.gnu.org/software/automake/#introduction (_emphasis_ added):

Automake is a tool for automatically generating Makefile.in files compliant with the GNU Coding Standards. _Automake requires the use of Autoconf._

From https://www.gnu.org/software/autoconf/autoconf.html#family (_emphasis_ added):
Autoconf is often used together with the following software systems:

...

GNU Automake _uses_ Autoconf.
This is consistent with Debian's and Ubuntu's package dependencies:

I can't comment on why your intuition is what it is without knowing more about what tools you were using, your understanding of how those tools worked, and what was already on the base images you used for those VMs, but I suspect your confusion stems from one or more of:
- automake was already installed;
- automake was getting pulled in as a dependency of something else; or
- you were indiscriminately installing "recommended" packages (in both Debian and Ubuntu, autoconf recommends automake, but it doesn't maintain a circular dependency for it)
I'm guessing it was the last one, because that is the default behavior for apt-get. However, relying on recommended packages breaks if you don't install them (e.g., you're aiming for a minimal system by using apt-get install --no-install-recommends ...).

If you're still unconvinced, try these. Excerpts:
