    The GOT holds the address in the PLT to be executed.
    The loader then gets:
    24(15) =  Pointer to the structure describing the object.
-   28(15) =  Offset in symbol table
+   28(15) =  Offset into rela.plt
 
    The loader  must  then find the module where the function is
    and insert the address in the GOT.
