sigwait is not called from any uclibc function, so "hidden symbol"
trick is not needed on it. __sigwait also is never used,
and it's not clear why it even existed.

  fix compilation of linuxthreads for sparc
  add myself to MAINTAINERS for sparc
........

* share Sys V semaphores in order to get appropriate SEM_UNDO semantics.
* correct guardaddr in pthread_free() for TLS case
* move spinlock unlocking before restart()
* When exit was called from a signal handler, the restart
  from the manager processing the exit request instead restarted the thread
  in pthread_cond_timedwait.
