commit 3266a463274789de3d805667a851c08bf5b36c18
Author: Matt Joyce <matthew.joyce@embedded-brains.de>
Date:   Tue Feb 1 12:37:46 2022 +0100

    Add _REENT_STDOUT(ptr)
    
    Add a _REENT_STDOUT() macro to encapsulate access to the _stdout
    member of struct reent. This will help to replace the struct
    member with a thread-local storage object in a follow up patch.
