Canonicalize i386-*-freebsd* to i586-*-freebsd* and refactor CPU handling for FreeBSD

[Gerald Pfeifer]

Hi guys,

this is my first patch for config and I'm not sure how you prefer
to get patches against the git repository, but hope this works?

I tested this by running the new config.guess on FreeBSD/i386 and 
FreeBSD/amd64 systems and verifying the output was adjusted in the 
former case and unchanged in the latter (plus a bootstrap and run
of GCC head with this script on i586-unknown-freebsd10.3).
