These functions were previously removed due to problems running the tests with `errno` in them. This was resolved previously by making the internal implementation of these functions use a global `errno` so that tests can still use `errno` functionality as long as they are run with a single thread. This allows us to re-enable these tests as a previous patch has also resolved the issue where the `stdlib` tests could not be hermetic due to the dependence on system rounding functions.
