microblaze: fix race condition in building boot images
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 because two threads descend into arch/microblaze/boot simultaneously. Add proper dependencies to avoid it.
