Stack unwinding that happens during NPTL thread cancellation needs
cancellable syscall wrapper functions to be compiled with -fexceptions
-fasynchronous-unwind-tables to be able to unwind to cleanup handlers
registered before syscall invocation.

Add these flags for all cancellable syscall wrappers.
