Eh, Linux *does* support that, from man host.conf (/etc/host.conf):
multi Valid values are on and off. If set to on, the resolv+
library will return all valid addresses for a host that appears in
the /etc/hosts file, instead of only the first. This is off by
default, as it may cause a substantial performance loss at sites with
large hosts files.
