I at least see configure called with:
--with-openssl-libdir=/usr/lib/x86_64-linux-gnu

And then outputting:
checking for openssl library directory... /usr/lib/x86_64-linux-gnu
checking for openssl include directory... /usr/include
checking if we will use crypto... yes
checking if linking with -lcrypto alone works... yes
checking for EVP_MD_do_all_sorted... yes
checking if we want to use OpenSSL's crypto random (if available)... yes

I have to admit I don't know why it works, why that variable is set.
Maybe dpkg-buildpackage sets this by default?
