toolchain: uClibc 0.9.32: Implement tiny /etc/gai.conf

Implement simplest variant of /etc/gai.conf to control IPv6/IPv4 names order
resolution. Unfortunately, it incompatible with glibc due it(glibc) hasn't
simple switch, just longest prefix matching list - consumes too much code.

Default names resolution behavior remains old - IPv6 first, IPv4 second.
To change it to IPv4 first, IPv6 second, create /etc/gai.conf containing
single line:

 precedence ipv4

Note: Manual file creation of gai.conf and copy to /etc/gai.conf.
Problem question, will this remain after reboot or future FW update.

Solved. I added in firewall script
cat << EOF > /etc/gai.conf
precedence ipv4
EOF

Output sample:
/opt/home/admin # nslookup wl500g-repo.googlecode.com

Address 1: 127.0.0.1 localhost.localdomain

I think it's easier to set 'strict-order' in dnsmasq configuration.
