I think the proper solution would probably to pass the path to
krb5-config:

    LIBTIRPC_CONF_ENV += KRB5_CONFIG=$(STAGING_DIR)/usr/bin/krb5-config

Could you look into that, please?

If that does not work, can you expand the commit log to explain why we
thus need to explicitly pass -l flags, and respin, please?

Regards,
Yann E. MORIN.
