> 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
# if we do not support shared) but we can tell it to allow the symbols used
# here to be undefined.
set extra_flags ""
if { [istarget *-*-darwin\[912\]*] } {
set extra_flags "-Wl,-U,_foo,-U,_bar"
}
...
