[ Upstream commit 64c3f648c25d108f346fdc96c15180c6b7d250e9 ]
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
Building powerpc:bamboo:smpdev:44x/bamboo_defconfig ... failed
------------
Error log:
arch/powerpc/boot/treeboot-akebono.c:37:20: fatal error:
libfdt.h: No such file or directory
arch/powerpc/boot/treeboot-currituck.c:35:20: 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.
