Interestingly, only the aarch64 blobs provide libgbm support. This
will help in fixing an issue that exists today, where ARM32 +
imx-gpu-viv + wayland + qt5 fails to build, because qt5 is told that
libgbm is available, i.e the following configuration:
BR2_arm=y
BR2_cortex_a9=y
BR2_ARM_ENABLE_VFP=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_QT5=y
BR2_PACKAGE_QT5BASE_GUI=y
BR2_PACKAGE_QT5BASE_EGLFS=y
BR2_PACKAGE_FREESCALE_IMX=y
BR2_PACKAGE_FREESCALE_IMX_PLATFORM_IMX6Q=y
BR2_PACKAGE_IMX_GPU_VIV=y
BR2_PACKAGE_IMX_GPU_VIV_OUTPUT_WL=y
# BR2_TARGET_ROOTFS_TAR is not set
fails to build during the qt5base configure step with:
ERROR: Feature 'gbm' was enabled, but the pre-condition 'libs.gbm' failed.
