This patch will fix a problem when the same host is defined with both IPv4 and
IPv6 entries in /etc/hosts. Previous only the first of these host would work,
as uClibc would read the /etc/hosts file from top to bottom, failing if the
first hit did not match the IP type.
Now uClibc will continue reading, even if the first correct entry name, but wrong IP
type fails. Thus, allowing a second correct entry name with correct IP type
will result in a name resolve.
