Comment:

 The link error appears to be associated with the known failure cases in
 tor's library detection.

 Adding an explicit `-L${OPENSSL_DIR}/lib` to the linker flags then reveals
 the actual likner issue with 1.1.0-dev:

 {{{
 Undefined symbols for architecture x86_64:
   "_BN_is_word", referenced from:
       _crypto_pk_public_exponent_ok in libor-crypto.a(crypto.o)
       _crypto_get_stored_dynamic_dh_modulus in libor-crypto.a(crypto.o)
 }}}

 I'll try to work out why this is happening.

 By the way, I'd like someone who knows a bit more about tor's makefiles
 and library detection to fix this one :-)
