Comment(by rl):

 I thought that `collect2` automates this. IIRC, it ploughs through all
 object files looking for specific constructor symbols and then generates
 and links in an additional module which calls those symbols and is, in
 turn, called at start up. Wouldn't it be enough to simply make sure that
 module initialiser symbols look like constructors and link with
 `collect2`?
