Actually I just don't see how the code in question could have ever
detected FreeBSD correctly, unless the normal OpenSSL build system
does some magic for this (which it doesn't seem to).
I'm doing "make universe" test builds with the patch below now.
I will try test this with actual hardware tomorrow (if I can find it),
but it's quite possible I won't have time until Friday to get
something set up to test. If somebody else can test the patch below
with some crypto hardware that would be great.
Thanks for the patch btw. :-).
