    Allow the macw and macl instructions to be used on CPUs that have emacs
support.

    From PR 22123:

      The common opcodes of emac and mac seem to be only implemented for mac.

      To reproduce:

        echo "macw %d3l,%a0l" > /tmp/dummy.S
        m68k-unknown-elf-as -m5208  /tmp/dummy.S

      Outputs something like:
        /tmp/dummy.S: Assembler messages:
        /tmp/dummy.S:1: Error: operands mismatch -- statement `macw %d3l,%a0l'
ignored

      This behavior occurs only if the CPU supports only emac but not
explicitly mac (but emac is a superset of mac).
