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.
