Having issues compiling on the lastest version of Debian 9

In omnibus we are getting this error:

This is on a fresh debian 9 docker image, with ruby 2.3.5

An older debian 9 with ruby 2.3.3 continues to work fine

I'm rebuilding the debian 9 docker image in case it was a fluke: https://dev.gitlab.org/cookbooks/gitlab-omnibus-builder/-/jobs/1435720

the old image was on debian 9.0, the failure is on debian 9.1

current directory:
/opt/gitlab/embedded/lib/ruby/gems/2.3.0/gems/allocations-1.0.5/ext/liballocations
make "DESTDIR=" install
make: /usr/bin/mkdir: Command not found

This seems like a broken environment?

mkdir is located in /usr/mkdir not /usr/bin/mkdir

Strange.

I was able to bundle install from a source install on the debian 9 docker image, but the omnibus build is still failing with this error. (Omnibus builds with its embedded libs and it's own ruby)

We do have a mkmf patch in omnibus that might be causing the issue, but debian 9 is the only failing build.

I also noticed our ruby build was being read from cache in omnibus, I'm going to try a build with fresh cache. (Will also show me which of our ruby patches are being applied)

A clean cache fixed it.

The problem is that on Debian 9.0, mkdir is in /usr/bin/mkdir, and 9.1 is in /usr/mkdir. If you use a ruby that had it's rbconfig generated on 9.0, rbconfig will have the wrong paths
