Yeah, that was exactly was I was trying to do 2 months ago (coincidentally also 
on an ARM device). I
also got everything to compile and if I remember it correctly I even got G.722 
to be standing in the
audio codec list.
But I unfortunately never got the codec really running which I don't 

I would also definitely be interested in having G.722 integrated in Linphone - 
even if it would be
with the help of a preprocessor switch or something. (Like USE_G722_CODEC)
