For anyone concerned, This problem came from trying to compile GCC/GNAT with AdaCore's GPL GNAT. Apparently AdaCore's version uses different names for things so symbols dont match up. I was able to get a native GCC/GNAT working just fine... and then cross compile using the newly built native. Moral of the story: dont mix Adacore and GCC.
