Isn't this the wrong test? Shouldn't you test for __NetBSD__ instead? AIUI _NETBSD_SOURCE is just a feature test macro like _GNU_SOURCE, right?

I can give you my Ack or RB after this, but FWIW I'm not a maintainer for EmulatorPkg so you'll still need appropriate reviews from the package mainainers.
