    ia64: Remove sigprocmask/sigblock objects from libpthread
    
    It is required because __libc_unwind_longjmp (used on thread
    cancellation) calls __sigprocmask.  Replace with a direct call.

    The sigblock function is not exported and is not used internally, so
    it can be removed.
    
    Checked on cross build for ia64-linux-gnu.
