* sysdeps/s390/s390-32/elf/start.S: Replace pc relative relocation

	by a GOT relocation to make Scrt1.o position independent.
	* sysdeps/s390/s390-64/elf/start.S: Likewise.

	* sysdeps/unix/sysv/linux/s390/s390-32/syscall.S: Add support for
	six system call parameters.
	* sysdeps/unix/sysv/linux/s390/s390-64/syscall.S: Likewise.
