I've looked if we couldn't we work around this by declaring another
static variable with __latent_entropy and use it to initialize
net_rand_state early, for example in prandom_init(), but there we
already fill net_rand_state with randoms so I'm wondering if that
__latent_entropy is used before prandom_init() or if its sole purpose
is to provide extra initial entropy to be combined with the one
prandom_init() will add.
