Can you please try reverting each of these Makefiles individually, and check when the problem disappears? The only effective change caused by this commit is that some CFLAGS might appear in a different order. It might be possible that one of the Makefiles involved is overly sensitive to this. My first guess would be gnu/lib/csu, and after that gnu/lib/libgcc. -Dimitry
