The problem in ‘make-bootstrap.scm’ 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
‘glibc-for-bootstrap’ & co. would use ‘glibc/hurd’.

Does that make sense?

Let me know how that works.

Thanks,
Ludo’.
