Makefile: Add NEEDS_CRYPTO_WITH_SSL
The Makefile comment for NEEDS_SSL_WITH_CRYPTO says to define it "if
you need -lcrypto with -lssl (Darwin)." However, what it actually
does is add -lssl when you use -lcrypto and not the other way around.
However, libcrypto contains a majority of the ERR_* functions from
OpenSSL (at least on OS X) so we need it both ways.
So, add NEEDS_CRYPTO_WITH_SSL which adds -lcrypto to the OpenSSL link
flags and clarify the difference between it and NEEDS_SSL_WITH_CRYPTO.
