Subject: [PATCH] Add some of the options to select optimizations of the C DES
 code for different architectures.

Doesn't help some platforms much, helps others quite a bit.  These
options are from options.txt in the libdes/libcrypto distribution; it
would probably be best to test and replace them with what's best with
the current gcc on each of our architectures.
