This would not help, because at the point when
  gl_LIBOBJS=`echo "$gl_LIBOBJS" | sed -e 's, , $gl_source_base/,g'`
is being run, $gl_source_base has the value 'gnulib-tests', not 'lib'.

Yes, the statement
  ac_config_libobj_dir=$gl_source_base
is also out of order.

It's probably not worth to try to fix the non-recursive-gnulib-prefix-hack
module in this direction. Please feel free to revert my change to
modules/non-recursive-gnulib-prefix-hack, and add a comment why 'lib' has
to be hardcoded in this place.
