I get this with a self-signed cert:

certs/Makefile:18: *** target pattern contains no '%'. Stop.

CONFIG_SYSTEM_BLACKLIST_HASH_LIST="tbs:8eed1340eef37c1dc84d996406ad05c7dbb3eade19132d688408ca2f63904869"

I used the script in 10/10 to test this, which is another
reamark: the patches are in invalid order, as you need to
apply 10/10 before you can test 8/10.
