Blackfin: reject outdated/unused/wrong relocation types

All kernel modules are required to be built with -mlong-calls and thus
should not generate any of these relocations.  If they do, it means the
module has not been compiled properly, so rather than trying to handle
them (and running into random run time errors) just error out on module
load to force the module to be compiled correctly.
