Not installing.  While the patch is fairly obviously correct,
glibc's ld.so expects relocs against local syms to be buggy.  :-(

Extract from dl-machine.h:

  /* The condition on the next two lines is a hack around a bug in Solaris
     tools on Sparc.  It's not clear whether it should really be here at all,
     but if not the binutils need to be changed.  */
  if (rinfo == R_PPC_RELATIVE
      || (sym->st_shndx != SHN_UNDEF
	  && ELF32_ST_BIND (sym->st_info) == STB_LOCAL))
    {
      /* Has already been relocated.  */
      Elf32_Word loadbase = map->l_addr;
      finaladdr = loadbase + reloc->r_addend;
    }
