At least on linux, go's native resolver follows a sane subset of glibc conventions like parsing /etc/nsswitch.conf, /etc/resolv.conf, /etc/hosts [1]. As long as your dns configuration is defined there, you won't notice much of a difference between go programs using go's resolver and programs making glibc library calls for dns stuff.
