As discussed on IRC, --target expect a =E2=80=9CGNU triplet=E2=80=9D such as
=E2=80=9Ci686-linux-gnu=E2=80=9D, so the above thing cannot work.

Note that cross-building from anything to i686 is untested, so it=E2=80=99s=
 not
a good choice.

Regardless, cross-building =E2=80=98bootstrap-tarballs=E2=80=99 to one of t=
he supported
target triplets works on master:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix build bootstrap-tarballs --target=3Dmips64el-linux-gn=
u -n
substitute: updating list of substitutes from 'https://mirror.hydra.gnu.org=
'... 100.0%
The following files would be downloaded:

See:

  https://hydra.gnu.org/job/gnu/master/mips64el-linux-gnu.bootstrap-tarball=
s-0.x86_64-linux
  https://hydra.gnu.org/job/gnu/master/mips64el-linux-gnuabi64.bootstrap-ta=
rballs-0.x86_64-linux

So normally, if you pass =E2=80=9C--target=3Dpowerpc-linux-gnu=E2=80=9D (or=
 whichever
triplet is appropriate), that should work too.

HTH!
