Add initial support for the FreeBSD/alpha kernel. This is very much a

work in progress and has never booted a real machine.  Initial
development and testing was done using SimOS (see
http://simos.stanford.edu for details).  On the SimOS simulator, this
port successfully reaches single-user mode and has been tested with
loads as high as one copy of /bin/ls :-).

Obtained from: partly from NetBSD/alpha
