Feature: include build-tools in list-dependencies

[pjljvandelaar]

My cabal file contains:

  build-tools:   alex
                      , happy

yet to my surprise this dependency is not reported when I use
stack list-dependencies

As a user, I would like to know the version of the build-tools that are needed to build my application.
Could you please add this feature!

Makes sense, thanks for the report!

I'd like to second this with an even more motivating use-case in my case:

I'm trying to build a project on FreeBSD which indirectly depends on happy, and stack fails the installation of happy with some linker errors. I tried both stack list-dependencies --depth=100 and stack dot --external in the hopes that I could figure out which of my dependencies depend further on happy, but I was surprised to see it not being in either of those outputs.

Edit: I've written with more details about my situation on StackOverflow -- linking here in case it is relevant.

Blocking this on #3777 , since I believe that will also solve this.
