Now that BIP66 passed, OpenSSL is no longer directly part of the
consensus. What matters is that DER signatures are correctly parsed, and
secp256k1 crypto is implemented correctly (as well as the other
functions we use from OpenSSL, such as random number generation)
This means that effectively, using LibreSSL is not a larger risk than
using another version of OpenSSL.
Remove the specific check for LibreSSL.
Includes the still-relevant part of #6729: make sure CHECK_HEADER is
called using the right CXXFLAGS, not CFLAGS (as AC_LANG is c++).
Zcash Note:
This includes a code removal from d9add719519e2019b1f353d8d6832dcfc88ee850
that was omitted from 5a3913361d during
backporting of bitcoin/bitcoin#6501 to 0.11.* in bitcoin/bitcoin#6703

What is Zcash?
Zcash is an implementation of the "Zerocash" protocol. Based on Bitcoin's code, it intends to offer a far higher standard of privacy and anonymity through a sophisticiated zero-knowledge proving scheme which preserves confidentiality of transaction metadata.
Zcash is unfinished and highly experimental. Use at your own risk.
