I started doing something like that, but gave up.  It's just too much
of a hassle.  I'd rather just fix the problem at hand, which occurs
with a native compiler, and hope no other compiler has this problem.
After all, we can always recommend GCC :-)

OTOH, it wouldn't hurt to run something like this on the binutils
tree (minimally tested; may require GNU grep and GNU sed):

grep -lr '\<0x[89a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z]\>' bfd opcodes binutils gas ld |
while read f; do
  sed 's,\<0x[89a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z][0-9a-zA-Z]\>,(unsigned)(N_ONES(32) \& &),g' \
    < $f > $f.new && mv $f.new $f
done
