i don't know how to do this with OpenSSL (afaict, the "openssl ca"
command does need an CSR to produce a cert).
But if you have access to the secret key for the CA, and you have the
raw public key of the would-be end-entity, you can produce a cert using
certtool (from the gnutls-bin package):
certtool --load-ca-privkey=ca-secret.key \
