Yes LibreSSl has the same apache license as OpenSSL

pkg-config is generally preferred anyway

OK I finally got around to looking through this (sorry for the delay I
previously hadnt had time) and everything looks good.
Since someone complains about LibreSSL not working with our OpenSSL support
every couple of months then this would be a welcome fix and in my opinion
this is the best way to support LibreSSL going forward. If Stefan is happy
to continue to support this in the future if needed then im on-board with
merging this.

If no one has any issues Ill merge this in a couple of days.
