How many multilib's does adding the v4e support add?
I hate to see another entire toolset binary just to get 1
or 2 multilib variants.

GNU/Linux is not the only OS interested in the v4e.
There should be a generic elf target (m68k-elf) and
I know the RTEMS community would like this (m68k-rtems).

It might make sense to add the multilib to the t-* files
of interest and add coldfire-XXX targets for smaller
dedicated toolsets.  It shouldn't be much besides a
new t-XXX file and a config.gcc entry if you can get
binutils and gdb to match.
