Thanks, this is interesting.

Now for some stupid questions:

 - does linking with gold instead (i.e., installing binutils-gold)
   change the outcome?

 - does using -Wl,--no-undefined in place of -Wl,-z,defs change
   anything?  Presumably -Wl,--no-undefined
   -Wl,--error-unresolved-symbols errors out --- what is the message
   when it does?

 - what does using "-z defs" buy us when the error is demoted to a
   warning by a later command-line option, anyway?  Though I still
   don't understand what is causing this code path to break.
