Motorola, in their infinite wisdom, decided to use the same mnemonic for 
the 68851/68030 pflusha coprocessor instruction and the 68040/060 pflusha
builtin, which have different encoding although quite similar semantics.

Same in a few other places.

The result is that we have to decide what CPU locore.s is assembled for,
and encode the other opcodes with .word sequences.

Try .word 0xf518 on 040/060
