I fixed a race condition in the parallel building of ARM in commit
3939f3345050 ("ARM: 8418/1: add boot image dependencies to not
generate invalid images").
I see the same problem for MicroBlaze too.
"make -j<N> ARCH=microblaze all linux.bin.ub" results in a broken build
since two threads descend into arch/microblaze/boot simultaneously.
Add proper dependencies to avoid it.
