My personal thinking is not a lot reliable, but I would notice two things.  
The first is that GCC stands for GNU C Compiler; and the second is that  
there were indeed some issue with the intermediate language it use, which  
shown (in the past), to not be very well suited for Ada or at least GNAT  
(or just its runtime?). There use to be some tweakeries to make it work  
properly with GCC, if my mind is right. Porting GCC or creating one which  
can target a platform, is one thing, doing the same for GNAT, although it  
uses GCC, is another. And that still not counting the libraries issues…  
(same story for both Ada and C, by the way). Porting or targeting, is not  
so simple, it involves many things, not just an intermediate language.  
This also depends a lot on the requirements, as you may understand (and as  
some people already pointed).
