Update.

	* Makerules (build-shlib-helper): Don't use -z defs linker option
	if no-z-defs is defined either.

	* sysdeps/unix/sysv/linux/s390/s390-64/kernel_stat.h: Remove unused
	file.

2003-01-10  Martin Schwidefsky  <schwidefsky@de.ibm.com>

	* sysdeps/unix/sysv/linux/s390/s390-32/syscalls.list: Add vfork.
	* sysdeps/unix/sysv/linux/s390/s390-64/syscalls.list: Likewise.
