As Richard pointed out, I raised this as potential general problem 
because the effects on GAS had not been discussed so far. In your 
specific case you're probably fine with the --with-cpu=arm9 setting. 
In contrast of your initial more subtle problem, the issue I mentioned 
has the advantage of giving a plain compile error so one would notice 
it.
