Once in a while I see build errors similar to the following when building images from a clean tree.
Building powerpc:virtex-ml507:44x/virtex5_defconfig ... failed
Error log: arch/powerpc/boot/treeboot-akebono.c:37:20: fatal error: libfdt.h: No such file or directory

Rebuilds will succeed.
Turns out that several source files in arch/powerpc/boot/ include libfdt.h, but Makefile dependencies are incomplete. Let's fix that.

For some reason I see the build error fixed with this patch more often lately. It would be great if you can apply it to v3.18.y and v4.4.y. Tested on both v3.18.y and v4.4.y.
Queued for both trees, thank you.
