It does, I even asked the meson devs to be sure. find_program()
respects the crossfile, unless `native: true` is added [2].

There's nothing special about `nm` here, it's just a program that can be
set via the crossfile, like `cc` or `ar`.
I guess the documentation on the cross-compilation page [1] could be
improved to make the behaviour of find_program() more explicit; care to
send a patch? :)
