Commit 5401dd7 does that.

There=E2=80=99s one difference compared to guix-package: guix-build doesn=
=E2=80=99t try
to parse =E2=80=9Csub-derivation names=E2=80=9D like guix-package does (aft=
er a
colon=E2=80=93see the manual), because that doesn=E2=80=99t make sense here=
 since
guix-build builds all the outputs of a derivation.

BTW, you could have used:

  guix-build -e '(@ (gnu packages libjpeg) libjpeg-8)'

Less convenient, but more efficient.

Thanks!
