Cross Compile for Windows - crypto not found
./configure --host=x86_64-w64-mingw32 

when running this command, crypto is not found.

```
checking for OPENSSL_init in -lcrypto... no
configure: error: in `/root/Tools/cpuminer/cpuminer-multi':
configure: error: could not find crypto

```

i have libssl-dev installed. without the host header all works well, as soon as I compile for windows, it errors out for me. I'm on a debian repo.
