dtc: add host build
Having a host variant of dtc is needed for example for U-Boot, which
uses the Device Tree for a number of platforms.
In addition, now that we have a proper host-dtc package, it is no
longer needed for the linux package to install the host dtc compiler:
users interested in having the host dtc compiler can simply enable
this package.
A Config.in.host option is added to build host-dtc, because the
initial reason why the host DTC built by the kernel was installed in
$(HOST_DIR)/usr/bin (commit 707d44d0a28906ebda49584dd5f55985406f0bde
from Thomas DS) was:
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.
[Thomas:
- rework the commit log.]
[Peter: keep the (renamed) linux version]
