Update.
	* sysdeps/unix/sysv/linux/s390/s390-32/sysdep-cancel.h (PSEUDO): Also
	defined symbol for entry point to avoid cancellation.
	* sysdeps/unix/sysv/linux/s390/s390-64/sysdep-cancel.h (PSEUDO):
	Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep-cancel.h (PSEUDO):
	Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep-cancel.h (PSEUDO):
	Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc32/sysdep-cancel.h (PSEUDO):
	Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/sysdep-cancel.h (PSEUDO):
	Likewise.
	* sysdeps/unix/sysv/linux/i386/not-cancel.h (__open_nocancel,
	__close_nocancel, __read_nocancel, __write_nocancel,
	__waitpid_nocancel): Add attribute_hidden.  If not in libc.so,
	libpthread.so or librt.so, define to corresponding function
	without _nocancel suffix.
	* sysdeps/unix/sysv/linux/s390/not-cancel.h: New file.
	* sysdeps/unix/sysv/linux/powerpc/not-cancel.h: New file.
	* sysdeps/unix/sysv/linux/sparc/not-cancel.h: New file.
