I don't think that is the case for V7-M architecture chips such as the
cortex-m3.  My V7-m manual (ARM DDI 0405B) does not have these instructions.  I
do not think it is a binutils bug.  This is an issue that the V7-M chips have a
different implementation of thumb2.  For example, they have udiv and sdiv,
which are in V7-R and V7-M only.
