and decrypt from OpenSSL. Right now we only build the 586 version,
but eventually we will be able to build the 686 version based on a
CPP flag defined as a result of using `cc -mcpu=pentiumpro'.
We don't build the assembly version of BF_cbc_encrypt(), as it would
have to be rewritten to be PIC.
Performance difference is quite noticeable.
