branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.02.x
Some Linux kernel configuration options (such as
CONFIG_SYSTEM_TRUSTED_KEYRING) require building a host program called
extract-cert, which itself needs OpenSSL.
Users having OpenSSL installed on their system won't see a problem,
but users who don't have OpenSSL installed will get a build
failure. This commit adds a new option that allows users to indicate
that their Linux configuration requires building host-openssl.

+ program called extract-cert, which itself needs
+ OpenSSL. Enabling this option will ensure host-openssl gets
+ built before the Linux kernel.
