There already *is* thread-local locale information in struc _reent.
Use it.  Only if something is missing, add it there.

No.

reent.h contains the definition of the _reent struct, which is what
constitutes thread-local storage in newlib.  You should make yourself
familiar with this structure and the available methods before adding
stuff.  struct _reent also contains a pointer to thread-local locale
information, the _locale member pointing to struct __locale_t, which is
defined in the usual headers.  Some thread-local locale stuff, especially
the mbstates, are in struct _misc_reent, pointed to by the _misc pointer
for historical reasons.

Please use what's available first, only add stuff if necessary.
