Summary

When building bind with LibreSSL 2.7 this results in build errors. The error is observed with versions 9.9 through 2018.04.06 76fa1c18

LibreSSL 2.7 implements the OpenSSL 1.1 API and adds a number of 1.0.2 methods as well. Most builds are now OK when using OPENSSL_VERSION_NUMBER >= 0x10100000 checks in the code. I've collected fall-out from the upgrade of LibreSSL 2.6 to 2.7 in the FreeBSD wiki (as well as patches to fix many ports).

Steps to reproduce

Build/install LibreSSL 2.7 in /usr/local

./configure --with-openssl=/usr/local
make

What is the current bug behavior?

openssldh_link.c:80:1: error: static declaration of 'DH_get0_key' follows non-static declaration
DH_get0_key(const DH *dh, const BIGNUM **pub_key, const BIGNUM **priv_key) {
^
/usr/include/openssl/dh.h:196:6: note: previous declaration is here
void DH_get0_key(const DH *dh, const BIGNUM **pub_key, const BIGNUM **priv_key);
     ^
etc.

What is the expected correct behavior?
