[patch] Add OpenBSD convenience platform

[James Turner <james@...>]

I looked through the archives so hopefully this hasn't been previously
suggested and rejected. The attached patch adds a new convenience
platform for OpenBSD. Right now the OpenBSD ports system includes a
similar patch but I figured it might be nice to have it as one of the
default platforms like FreeBSD. Thanks.
