commit a3fe1ed573dddcfd905183e6b5fa60bd7cfa661d
Author: Sebastian Huber <sebastian.huber@embedded-brains.de>
Date:   Wed May 18 19:21:44 2022 +0200

    Move content in <sys/reent.h>
    
    Move definitions not directly related to struct _reent to the bottom of the
    file.  This allows a contiguous #ifndef _REENT_THREAD_LOCAL_STORAGE block.
