Fixes CVE-2019-13917:
http://www.exim.org/static/doc/security/CVE-2019-13917.txtd185889f47
added new code to "Prebuild the data structure for builtin macros".
This function needs a host-built binary called macro_predef, it depends
on host-berkeleydb, host-pcre and optionally on host-openssl.
With an openssl-enabled exim the host build of macro_predef will fail
if host-openssl is missing:
/usr/bin/gcc -DMACRO_PREDEF macro_predef.c
In file included from hash.h:14,
from exim.h:485,
from macro_predef.c:11:
sha_ver.h:37:12: fatal error: openssl/ssl.h: No such file or directory
because macro_predef also has the an optional dependency on openssl:
