The Vivante GPU is used as kernel module for all i.MX6, by default, so
the defconfig should not enable it as other SoC (as i.MX6UL and
i.MX7D) uses the same defconfig and does not have the Vivante GPU.
This avoids the built-in driver build for other SoCs, thus fixing a
build error with GCC 6, which is hidden when using the external
module.
