Finally remove auto-home-host 

This was #if-ed out for 3.0, but it really should go.
Gcc 4.6.0 complains that auto_update_home is set but not used
(which is true).

If
.I mdadm
cannot find any array for the given host at all, and if
.B \-\-auto\-update\-homehost
is given, then
.I mdadm
will search again for any array (not just an array created for this
host) and will assemble each assuming
.BR \-\-update=homehost .
This will change the host tag in the superblock so that on the next run,
these arrays will be found without the second pass. The intention of
this feature is to support transitioning a set of md arrays to using
homehost tagging.
The reason for requiring arrays to be tagged with the homehost for
auto assembly is to guard against problems that can arise when moving
devices from one host to another.
..
Note: Auto assembly cannot be used for assembling and activating some
arrays which are undergoing reshape. In particular as the
.B backup\-file
