I was updating the Commentary (commentary/ and found this

    To find out which packages are currently zero-boot packages, do
    the following in a GHC build:

    $ make show VALUE=BOOT_PKGS

Since `make` will go away eventually, I wanted to tell people how to
discover zero-boot packages using Hadrian.
