that was then .. and now I'm off to working around this issue in a
really cheap way :)

Awk understands `$ 1' just as well as `$1', but the shell does not
expand the former, so..

OK to apply to HEAD (untested, but I'll test before commit)?

        <export_symbols_cmds>: Work around shell expansion issue in
