Having dtc as a host tool can be useful for users that have a custom
boot scenario where the device tree is not embedded in the kernel.

v2: remove old parameters to GENTARGETS call, sorry.
v3: rename Config.in.host and depend on Linux (comments Arnout)
v4: no need for a separate package, just put the logic in linux.mk
(suggestion of Alexandre Pereira da Silva, thanks!)
