Subject: [PATCH] Fix static linking with OpenSSL

Adjust link order of libz to solve bug with static linking
and remove host paths when looking for openssl.

[Vincent:
 - Adapt the patch to make it apply on the new version.]
[Bernd: rebased for tor-0.2.7.6, 0.2.8.10, 0.2.9.9, 0.3.1.7, 0.3.2.10 &
        0.3.4.8, 0.3.5.7]
[Fabrice: fix detection of openssl functions in 0.3.5.8]
