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).
