If using the libc for Noux programs, the default implementation of these functions cannot be used because they rely on a dedicated timeout-scheduler thread. Noux programs, however, are expected to contain only the main thread. By turning the functions into weak symbols, the noux libc-plugin can provide custom implementations.
