scripts/sign_data.sh is just a wrapper to do this:
./signature_digest_utility $1 $3 \
| openssl rsautl -sign -pkcs -inkey $2
AFAICT, that script is only invoked by the SignatureFile()
function in host/lib/file_keys.c, which is not referenced by
anything. I think I can remove both of those things.
Also remove utility/gbb_utility.cc, which should have been done
long ago in commit 6f39615.
BUG=none
BRANCH=ToT
TEST=make runalltests
Also ran it on daisy_spring-paladin and link-tot-paladin.
