Yes, albeit some cleaning up in gas may be needed (along the lines of
other cleanup I already did there not so long ago, and also along the
lines of more related cleanup that wants doing). If you want to be able
to use -march=iamcu, you need to enable that target as a secondary one.
(I actually question that it was a good move to make iamcu a secondary
target about everywhere in the first place. It is a distinct target.)
