This is kind of weird but I don't think there is a good solution here.
It's strange to use a script with a relocateable link and if you do
use a script its clearly best to not have an orphan section. I
suppose this is OK. I do sort of wonder why GNU ld does, but it's
hard to care very much. Thanks.
