Yeah, you need the openssl-devel package now. There's some stuff using the
library directly allows us to do that you can't do with just the command line

This is mentioned in the

MODSIGN: Provide a utility to append a PKCS#7 signature to a module

commit description.

Note that the utility is written in C and must be linked against the
OpenSSL crypto library.

Would it help to update the module-signing.txt document, the config option or
the git pull request/cover note?
