3.18-stable review patch. If anyone has any objections, please let me know.

[ 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.
