Thanks to @velrest we found the culprit:

  version "1.2.1"
  resolved "https://registry.yarnpkg.com/ember-adcssy/-/ember-adcssy-1.2.1.tgz#7b6d2a1f9cb43434ddf5c6e5e1614458849965d1"

Seems to be a lock-file issue.

The dependency in the package.json is already correct.
"ember-cli-postcss": "^4.0.0",

ember-cli-postcss@^4.0.0:
  version "4.0.0"
  resolved "https://registry.yarnpkg.com/ember-cli-postcss/-/ember-cli-postcss-4.0.0.tgz#d32c4ab5539122e3bc8fe26bb9cc18d8ac377739"
  dependencies:
    broccoli-file-creator "^2.1.1"
    broccoli-merge-trees "^3.0.0"
    broccoli-postcss "^3.5.3"
    broccoli-postcss-single "^1.6.0"
    ember-cli-babel "^6.12.0"
    merge "^1.2.0"

broccoli-postcss "^3.5.3"

I tried manually cleaning up the yarn.lock file but to no avail.
