[PATCH 2/3] Reentrancy, conditionally provide default __getreent() implementation

[Pekka Seppänen]

Conditionally provide default __getreent() implementation only if
_REENT_THREAD_LOCAL is not defined.  If struct _reent is replaced by
dedicated thread-local objects neither the structure nor _impure_ptr is
available.
