[Buildroot] [PATCH v2] Add dtc (device tree compiler) as host tool

[Buildroot] [PATCH v2] Add dtc (device tree compiler) as host tool

[Thomas De Schampheleire]

The dtc is taken from the Linux kernel sources and simply copied to the host
directory.
Having dtc as a separate host tool can be useful for users that have a custom
boot scenario where the device tree is not embedded in the kernel.

 The file should be called Config.in.host, like the other host tools.

 This should depend on BR2_LINUX_KERNEL, including the appropriate 
comment.
