    NPTL: fix CFLAGS for cancellation points
    
    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.
