I could reproduce the failure as well on my Alpine Linux, using simply

	$ make ARCH=arm CROSS_COMPILE=arm-none-eabi- mx6sabresd_defconfig
	$ make ARCH=arm CROSS_COMPILE=arm-none-eabi-

No separate object directory is used.

	$ make --version

This seems to have something to do with the RISC-V failures I tried to
fix days earlier[1], cherry-picking the patch also fixes this failure.
