The problem in =E2=80=98make-bootstrap.scm=E2=80=99 is that %glibc-stripped=
 and all the
%*-bootstrap-tarball variables are evaluated at the top level, thus
based on the default values of %current-system and
%current-target-system ("x86_64-linux" and #f here, whereas you would
like "i686-gnu" for the latter.)

One solution would be to turn all of these into procedures.  That way,
%current-target-system would have the value you expect, and so
=E2=80=98glibc-for-bootstrap=E2=80=99 & co. would use =E2=80=98glibc/hurd=
=E2=80=99.

Does that make sense?

Let me know how that works.

Thanks,
Ludo=E2=80=99.
