Why did you patch OpenSSL?

Looks like you've found a combination that does not enable couple of
crypto functions. I'll see what can be done about that in the Makefile.
As a workaround, you can build this by adding TLS_FUNCS=y into this
.config or if you use OpenSSL, you can also use NEED_CRYPTO=0 which will
result in linking less unneeded code (but does not apparently work with
internal TLS/crypto).
