Same comment as earlier regarding ‘bootstrap-origin’ and the URL.

Woow.  :-)

Here you can avoid ‘bootstrap-origin’ too and add mirror://gnu URLs.

The “new style” (with gexps) doesn’t work well with non-package inputs
in the sense that you cannot use ‘this-package-input’ to access them.

However, it might be simpler to not have them in ‘native-inputs’ and to
instead refer to them in the code, as in:

  #~(begin
      …
      (invoke "tar" "xvf" #$mescc-tools)
      …)

where:

  (define mescc-tools
    (origin …))

> +stage0-posix builds hex0, kaem, hex1, catm, hex2, M0, cc_x86, M1,
> +M2, get_machine, (mescc-tools), and M2-Planet.")

Bonus points if you can make it a full sentence.  :-)

(I feel ridiculous commenting on this on a patch series that’s this
important, but hey!)
