(In reply to Francois-Xavier Coudert from comment #23)
> It's not being passed -shared on darwin:

Then that means the shared effective target doesn't work properly on darwin
then.
It even has hacks for darwin in it though:
    # Darwin's linker defaults to error on undefined (which makes it look as
    #=C2=A0if we do not support shared) but we can tell it to allow the sym=
bols used
    # here to be undefined.
    set extra_flags ""
    if { [istarget *-*-darwin\[912\]*] } {
      set extra_flags "-Wl,-U,_foo,-U,_bar"
    }
