commit: http://git.buildroot.net/buildroot/commit/?id=88d350ca3ccdd91fd78ecf3e24e31e27726c5bc8
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The option BR2_LINUX_KERNEL_INSTALL_TARGET used to install the kernel in
/boot in the rootfs. The introduction of the device tree builds made it
possible to generate device tree blobs, and stored them in IMAGES_DIR
like the kernel, but didn't copy the dtb in /boot when _INSTALL_TARGET
was enabled.
