In fact, BR2_PACKAGE_POLICYCOREUTILS=y is not at all a requirement for
a working SELinux system. While host-policycoreutils is needed to have
the setfiles utility that you use below, having policycoreutils on the
target is not needed. So I've simplified this condition to:

ifeq ($(BR2_PACKAGE_REFPOLICY),y)

While it doesn't hurt, I don't think it makes sense to have "refpolicy"
in the dependencies here. Indeed, all this rootfs creation logic
happens after all packages have been built. Due to the
BR2_PACKAGE_REFPOLICY=y condition above, we know refpolicy is enabled,
and therefore it has already been built prior to the rootfs being
generated.

The ROOTFS_xyz_DEPENDENCIES are mainly useful for dependencies on host
tools that are needed to generate the root filesystem. Which is the
case here with host-policycoreutils. So I've simplified to:

ROOTFS_COMMON_DEPENDENCIES += host-policycoreutils

Applied with those changes. Thanks!

Thomas
