Coincidentally I think I need to split the $authz-obj-y variable into
two parts

 authz-obj-y containing only base.o
 authz-obj-impl-y containing everything else

Most things will thus be satisfied by just $authz-obj-y. Only the
system emulators and qemu-nbd then need to have authz-obj-impl-y

This will avoid qemu-img, qemu-io, and other tools and linux-user
from having to link to the pam library.

Regards,
Daniel
