It's possible that the default_environment[] array contains multiple entries for the same variable, e.g. a setting from env_default.h based on some CONFIG_* variable, and another from CONFIG_EXTRA_ENV_SETTINGS. In such a case, the last setting takes effect. Hence, in order to be able to use the output from this script as an CONFIG_DEFAULT_ENV_FILE and get the same default environment as one currently has, we need to preserve the order. So only sort by the variable name, and disable the last-resort comparison. We could pipe the result through uniq to remove duplicate lines, but I think there's some value in seeing that certain variables are defined multiple times.
