Looking at the breaking change:

+// On ARM we expect that you're using Clang if you want SkJumper to be fast.
+// If you are, the baseline float stages will use NEON, and lowp stages will
+// also be available. (If somehow you're building for ARM not using Clang,
+// you'll get scalar baseline stages and no lowp support.)

Well clearly the fallback was not tested.
