Note the build log itself isn't very useful, how the sizeof (long long) test fails might be interesting as well as sharing configury in a more direct way than looking at the build log. Bisecting also might help ... eventually related is PR94042 which had a bisection so you might try if that bisection applies to m68k as well.
