#     random32: remove net_rand_state from the latent entropy gcc plugin
#     
#     It turns out that the plugin right now ends up being really unhappy
#     about the change from 'static' to 'extern' storage that happened in
#     commit f227e3ec3b5c ("random32: update the net random state on interrupt
#     and activity").
#     
#     This is probably a trivial fix for the latent_entropy plugin, but for
#     now, just remove net_rand_state from the list of things the plugin
#     worries about.
