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.
