Before, loading a module would be guarded by an optional platform condition. This made it possible to avoid loading and evaluating a module if it did not support the host platform. Unfortunately, this made it impossible to share a single configuration between GNU/Linux and Darwin hosts, which some wish to do. This removes the conditional load and instead inserts host platform assertions in the modules that are platform specific. Fixes #1906
