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.
