It took me a little while to remember why...

I have actually written the explanation in 
http://sourceware.org/ml/binutils/2008-05/msg00193.html

In short, gas can convert some symbols in STT_SECTION in some cases. But 
after that, we can't tell whether the code pointed to by such a symbol 
is in ARM mode or in Thumb mode; hence we don't know what type of stub 
to insert.

Maybe I should update the comment to make it clearer.
