Fix errno thread-safety under AIX

Unlike Linux or Solaris, errno under AIX is not thread-safe by
default.

This patch sets _THREAD_SAFE_ERRNO when AIX is detected in order to
force the thread-safe implementation of errno. Without this, calls
like stat() in the rrdtool plugin fail with errno incorrectly set,
leading to the inability to create previously absent rrd files.

Maybe _THREAD_SAFE should be set instead, to prevent other possible
threads-related problems, but this is enough to scratch my current
itch...

Here is the relevant part of /usr/include/errno.h on AIX:

 #if defined(_THREAD_SAFE) || defined(_THREAD_SAFE_ERRNO)
 /*
  * Per thread errno is provided by the threads provider. Both the extern
  * int
  * and the per thread value must be maintained by the threads library.
  */
 extern  int     *_Errno( void );
 #define errno   (*_Errno())

 #else

 extern int errno;

 #endif  /* _THREAD_SAFE || _THREAD_SAFE_ERRNO */
