Partial relro support for gold
Now it is, As Andreas Krebbel did with ld, This patch separate .got and
.got.plt sections, swap them and assign the 3 magic GOT entries at the
beginning of .got section so _GLOBAL_OFFSET_TABLE_ will point to the beginning
of all GOT entries.
Same as ld after relro support the GOT layout in gold now look like this with
this patch:
+----------------------------------+
|got[0]: DYNAMIC | <--- _GLOBAL_OFFSET_TABLE_ ==
DT_PLTGOT .got
|got[1]: link_map parm |
|got[2]: &_dl_runtime_resolve |
+----------------------------------+
| | non-plt GOT entries
| |
| |
+----------------------------------+
| | <--- .gotplt, PLT GOT entries
| |
| |
