link to ld.so if that is not the installed name.
(lib-noranlib): Depend on the installed name in the build directory
instead of on ld.so.
* Makeconfig (link-libc): Include $(elfobjdir)/$(rtld-installed-name)
between libc.so and libc.a, because with libc.so's DT_NEEDED for ld.so
ld searches libc.a before ld.so (is that an ld bug?).
Add $(elfobjdir) to -rpath-link.
* Makerules (elfobjdir): Define as . when $(subdir) is elf.
* sysdeps/i386/dl-machine.h (elf_machine_rel): In R_386_32 case when
relocating _dl_rtld_map, subtract SYM's value from final reloc value,
but don't change *RELOC_ADDR before calling *RESOLVE, because it might
call the function we are relocating!
