If I'm not mistaken, your problem comes from the fact you're emerging shadow
with the su USE flag while having util-linux installed with the same USE flag.
Since that flag enables building the "su" program, it be set for both packages.
I think what you should disable the "su" flag for either shadow or util-linux.
On my system, I have it on for util-linux and not for shadow.
I hope this helps
