3209 relocation should be located at the child vtable.
3211 VTABLE_ENTRY is a zero-space relocation that describes the use of a
3212 virtual function table entry. The reloc's symbol should refer to the
3213 table of the class mentioned in the code. Off of that base, an offset
3214 describes the entry that is being used. For Rela hosts, this offset
3215 is stored in the reloc's addend. For Rel hosts, we are forced to put
3216 this offset in the reloc's section offset. */
