[PATCH v4 2/3] openssl: configure engine packages during install

Sun Feb 20 16:09:29 PST 2022
This enables an engine during its package's installation, by adding it
to the engines list in /etc/ssl/engines.cnf.d/engines.cnf.
The engine build system was reworked, with the addition of an engine.mk
file that groups some of the engine packages' definitions, and could be
used by out of tree engines as well.
