Done, sorry about that!

Should be possible.  The thing is, =E2=80=98make dist=E2=80=99 should alway=
s bundle
everything.  Another complication is that on x86_64 it=E2=80=99s interestin=
g to
have both i686 and x86_64 binaries...

Indeed.

Note that you can also do:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (use-modules (guix utils) (guix base32))
scheme@(guile-user)> (use-modules (rnrs io ports))
scheme@(guile-user)> (call-with-input-file "bootstrap/i686-linux/mkdir"
                       (compose bytevector->nix-base32-string sha256 get-by=
tevector-all))
$3 =3D "13ls4166y7gnykfphzmr0y7pn8kyikp5px4prnnhj1jyk5vhdgfm"
--8<---------------cut here---------------end--------------->8---

Granted, it=E2=80=99s more verbose.  :-)

Maybe we need a command-line interface to that?
