why does -mcfv4e work for gas but not objdump?

[Peter Barada]

I'm having trouble tryng to figure out why -mcfv4e works for gas, but
I have to specify -mm68k:mcfv4e for objdump to select the ColdFire v4e
version of the m68k tools.

In bfd/cpu-m68k.c I've added:

    N(bfd_mach_mcfv4e, "m68k:cfv4e",  FALSE, 0),

and am wondering if I add the following to get objdump to parse -m5407
is the correct way to solve this:

    N(bfd_mach_mcfv4e, "cfv4e",  FALSE, 0),

Any suggestions are appreciated.
