ia64: Remove sigprocmask/sigblock objects from libpthread

Browse Source 
It is required because __libc_unwind_longjmp (used on thread
cancellation) calls __sigprocmask.  Replace with a direct call.

They are required because __libc_unwind_longjmp (used for thread
cancellation) calls __sigprocmask.  Replace this 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.
