Do the CPU-specific optimization flags a better way, suggested by Simon Burge.

Add support for building the assembly versions of Blowfish encrypt 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.
