How is this related to  the addition of the host package? This seems
unrelated. Why is this needed now?

Why is this not needed for the target package ?

This makes me think we should probably have some inheritance of those
variables between the target variant and the host variant of the
package.

However, HOST_RUNC_TAGS = $(RUNC_TAGS) looks most likely wrong. Indeed:

ifeq ($(BR2_PACKAGE_LIBAPPARMOR),y)
RUNC_DEPENDENCIES += libapparmor
RUNC_TAGS += apparmor
endif

ifeq ($(BR2_PACKAGE_LIBSECCOMP),y)
RUNC_TAGS += seccomp
RUNC_DEPENDENCIES += libseccomp host-pkgconf
endif

and you most likely don't want HOST_RUNC_TAGS to contain apparmor or
seccomp, because we are not building libseccomp or libapparmor for the
host.

Best regards,

Thomas
