Update.
2001-08-26 Ulrich Drepper <drepper@redhat.com> * config.h.in: Add HAVE_Z_COMBRELOC. * configure.in: Add test for -z combreloc. * sysdeps/i386/dl-machine.h (elf_machine_rel): Minor cleanups and optimizations. Use HAVE_Z_COMBRELOC to avoid generaton of R_386_RELATIVE handling for ld.so startup.
