Yes.  Isn't there a way to detect OpenSSL version >= 1010003f?
I see there's already code in configure.ac that does this:

	#if OPENSSL_VERSION_NUMBER < 0x0090807f /* 0.9.8g */

Answering to myself.  Yes, there's a way.  Install package:

	libssl1.0-dev

That will (if installed) remove package libssl-dev which points to 
openssl >= 1.1.0.
