Update.
2003-07-04  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/s390/s390-32/elf/start.S: Emit position independent code
	if PIC.
	* sysdeps/s390/s390-64/elf/start.S: Likewise.

2003-07-07  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/powerpc/powerpc64/elf/start.S: Put L(start_address)
	into .data.rel.ro.local section if PIC to avoid DT_TEXTREL.
