Update.
2001-08-24 Ulrich Drepper <drepper@redhat.com> * elf/do-rel.h (elf_dynamic_do_rel): If not relocating lazily, don't call elf_machine_rel for the last DT_RELCOUNT relocations but instead elf_machine_rel_relative. * sysdeps/alpha/dl-machine.h: Define elf_machine_rel_relative. Minor optimizations. * sysdeps/arm/dl-machine.h: Likewise. * sysdeps/cris/dl-machine.h: Likewise. * sysdeps/hppa/dl-machine.h: Likewise. * sysdeps/i386/dl-machine.h: Likewise. * sysdeps/ia64/dl-machine.h: Likewise. * sysdeps/m68k/dl-machine.h: Likewise. * sysdeps/mips/dl-machine.h: Likewise. * sysdeps/powerpc/dl-machine.h: Likewise. * sysdeps/s390/s390-32/dl-machine.h: Likewise. * sysdeps/s390/s390-64/dl-machine.h: Likewise. * sysdeps/sh/dl-machine.h: Likewise. * sysdeps/sparc/sparc32/dl-machine.h: Likewise. * sysdeps/sparc/sparc64/dl-machine.h: Likewise.

Unfortunately as binutils tries to work around Solaris
dynamic linker bug which resolves R_SPARC_RELATIVE as X += B + A
instead of X = B + A this does not work any longer, since ld
clears it.

The following method relies on the fact that sparcv9 ABI maximal
page length is 1MB and all ELF segments on sparc64 are aligned
to 1MB. Also, it relies on _DYNAMIC coming after _GLOBAL_OFFSET_TABLE_
