Would you mind to explain, why you need this, rsp. why the current default
multilibs do not suffice your needs?
Adding a multilibs to the default set of multilibs needs of a target needs to
be very well motivated and can not be done light-heartedly.
Knowing you actually are working with lm32-rtems and not with lm32-* targets,
provided you can sufficiently motivate this change, raises the question if it
would not actally be more appropriate to extend the lm32-rtems multilib set
instead of the general set of multilibs.

(In reply to comment #1)
I'm sorry, but are you really trying to argue that libraries like libc and libm
MUST ALWAYS use the software emulation of the divider and sign extender (even
if their hardware versions are available on the CPU), as not applying this
change would imply?
The reason is simple, if you haven't guessed it: speed (and code size, but this
matters less). Not for me only, but for everyone else as well.
