assemble: support arrays created with --homehost=any

If an array is created with --homehost=any, then --assemble and
--incremental will treat it as being local to 'this' host, no matter
what the name of this host is.

This is useful for array that will be given unique names and be
moved between machines.

This needs to be documented.
