While this deals with a specific product (Oracle VirtualBox) the problem, and solution, appears to be more generically Ubuntu related.
When I purchased my laptop, running Ubuntu 16.04 LTS, a couple of years ago one of the first things I did was install Oracle VirtualBox. Have upgraded it several times since, and have never had a problem with it from Day One. Then a few days ago (have not used it in a few weeks) I needed to do some work with one of the VMs created under Vbox. The Vbox control console opened just fine, but when I tried to start any one of the VMs, I got this:

The man page for make says nothing about 'oldconfig' or 'prepare', and doing a little googling about it what I find sounds like it can be pretty dangerous to your system if you don't take a lot of precautions.make[1]: warning: -jN forced in submake: disabling jobserver mode.
