2791 VTABLE_ENTRY is a zero-space relocation that describes the use of a
2792 virtual function table entry.  The reloc's symbol should refer to the
2793 table of the class mentioned in the code.  Off of that base, an offset
2794 describes the entry that is being used.  For Rela hosts, this offset
2795 is stored in the reloc's addend.  For Rel hosts, we are forced to put
2796 this offset in the reloc's section offset. */
