#20987: Number precision of busybox awk is too low for x86-kvm_guest

-------------------------+------------------------
It looks like the busybox awk is broken for `x86-kvm_guest` in that it can
not even handle 32 bit integers arithmetic properly. It's bad because
`ipcalc.sh` depends on it and we need it to generate configs for
`dnsmasq`.
Here are the related output in `kvm_guest`.
{{{
root@OpenWrt:/# ipcalc.sh 192.168.1.1 24 100 149
IP=0.0.0.1
NETMASK=0.0.0.255
BROADCAST=0.0.0.255
NETWORK=0.0.0.1
PREFIX=24
START=0.0.0.101
END=0.0.0.250
root@OpenWrt:/# echo | awk -e 'END { v=3232235776; print v "," lshift(v,8)
}'
3.23224e+09,0
}}}
Expected output from an `ar71xx` target
