Which object files contain references to those symbols? (running each
through "nm" should show you).

There's a definition of va_copy in defines.h which should be activated when
the platform doesn't have it:
#ifndef HAVE_VA_COPY
# ifdef HAVE___VA_COPY
# define va_copy(dest, src) __va_copy(dest, src)
# else
# define va_copy(dest, src) (dest) = (src)
# endif
#endif
I suspect there's a file which should have includes.h at the top but
doesn't.
I think the EC_KEY_free should be fixed by this:
diff --git a/kex.c b/kex.c
index 2618e22..cf04574 100644
--- a/kex.c
+++ b/kex.c
@@ -432,8 +432,10 @@ kex_free(struct kex *kex)
#ifdef WITH_OPENSSL
if (kex->dh)
DH_free(kex->dh);
+# ifdef OPENSSL_HAS_ECC
if (kex->ec_client_key)
EC_KEY_free(kex->ec_client_key);
I should be able to reproduce the problem by building against the exact
openssl version you have.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
