You might need the following, to still build with LibreSSL.
That was my experience anyway, when I recently prepared similar fixes
for OpenSSL 1.1 and Apache Traffic Server.
#if OPENSSL_VERSION_NUMBER < 0x10100000L || defined(LIBRESSL_VERSION_NUMBER)

Library initialization functions are deprecated in openssl 1.1.0 API, as
initialization is handled by openssl internally.
Symbols for deprecated functions are not exported if openssl is built with
`--api=1.1 disable-deprecated`, so their use will cause a build failure.
