Deleting (unlinking) files doesn't make them go away. If something has the file open, it will prevent re-allocation of the files resources until the file is closed. libc should still be accessible to getty and any other application using it (including the OS). Note that an unlinked file cannot be closed and re-opened even within the same process.
