I have just updated my copy of EABI, and saw the sentence you are 
referring to.

So this means that the sample code you provided in 
http://sourceware.org/ml/binutils/2009-02/msg00224.html should also have 
a variant for Thumb -> Thumb stub (pic and non-pic) on V4T.

I'll give a look at that.

Thanks
