both use the same busybox 1.19.2
Looking at the source busybox-1.19.2/networking/nslookup.c it's simply not possible that the output of system 1 comes from busybox 1.19.2.

By the way, the applet nslookup is misleading, because it uses getaddrinfo instead of a DNS query. As a consequence, there are even answers from non existing DNS-servers.

# nslookup localhost 0.0.0.0
Server:    0.0.0.0
Address 1: 0.0.0.0

Name:      localhost
Address 1: 127.0.0.1 localhost
