However, external scripting may well rely on the existence of a device tree compiler as $(HOST_DIR)/usr/bin/dtc, regardless of its source. Changing these external scripts to use linux-dtc means that the scripts need to be aware of the buildroot release they are working with, which is not very nice. Add a symlink dtc->linux-dtc when no $(HOST_DIR)/usr/bin/dtc is present. When host-dtc is not enabled, the end result will be dtc and linux-dtc representing the same thing. When host-dtc is enabled, either it is build before linux and no symlink is created at any time, or it is build after linux, and the 'install' command in host-dtc will overwrite the symlink with a proper dtc. In both cases, the end result will be dtc and linux-dtc representing a different thing.
