TYPE is in the class ELF_RTYPE_CLASS_PLT if it can describe a
relocation for a PLT entry, that is, for which a PLT entry should not
be allowed to define the value. The GNU linker for CRIS can merge a
.got.plt entry (R_CRIS_JUMP_SLOT) with a .got entry (R_CRIS_GLOB_DAT),
so we need to match both these reloc types.
