Ok, first shot, see attached patch.

With this,
this works:    export GNULIB_SRCDIR=path/to/gnulib; ./bootstrap
--skip-po --copy --no-git
this likewise: ./bootstrap --gnulib-srcdir=path/to/gnulib --skip-po
--copy --no-git
this fails:       ./bootstrap --skip-po --copy --no-git

(where 'works' means octave is bootstrapping correctly for a unpacked
.tgz source tree)

correct direction?
