Makefile:969: recipe for target 'vmlinux' failed
NXP 4.9 kernel does not properly support mx31, so better remove this target.
mx31_3stack board is currently supported in U-Boot and kernel mainline,
so if someone is interested on this board, then a target can be introduced
later which uses these mainline components.
Currently I do not have access to this board, so remove it its defconfig
for now.
