 * Relocation types used in the m98k implementation.  Relocation entries for
 * things other than instructions use the same generic relocation as discribed
 * above and their r_type is RELOC_VANILLA.  The rest of the relocation types
 * are for instructions.  Since they are for instructions the r_address field
 * indicates the 32 bit instruction that the relocation is to be preformed on.
 * The fields r_pcrel and r_length are ignored for non-RELOC_VANILLA r_types.
