Subject: Support _REENT_THREAD_LOCAL Newlib configuration

In case the Newlib _REENT_THREAD_LOCAL configuration option is enabled, the
struct _reent is not defined (there is only a forward declaration in
<sys/reent.h>).  Instead, the usual members of struct _reent are available as
dedicatd thread-local storage objects.

Update #4560.
