    gdb: fix dwarf2/cooked-index.c compilation on 32-bit systems
    
    The i386 builder shows:
    
        ../../binutils-gdb/gdb/dwarf2/cooked-index.c: In member function ‘void cooked_index_vector::dump(gdbarch*) const’:
        ../../binutils-gdb/gdb/dwarf2/cooked-index.c:492:40: error: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 2 has type ‘std::__underlying_type_impl<sect_offset, true>::type’ {aka ‘long long unsigned int’} [-Werror=format=]
          492 |       gdb_printf ("    DIE offset: 0x%lx\n",
              |                                      ~~^
              |                                        |
              |                                        long unsigned int
              |                                      %llx
          493 |     to_underlying (entry->die_offset));
              |     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
              |                   |
              |                   std::__underlying_type_impl<sect_offset, true>::type {aka long long unsigned int}
    
    The die_offset's underlying type is uint64, so use PRIx64 in the format
    string.
