But host-dtc depends on host-bison and host-flex, which in turn bring host-m4. In total, on my machine, the time to build host-dtc from a clean build is almost one minute. Not a big amount of time. But FIT images are not that common, and one key aspect of Buildroot is its build time, which we try to keep low by making sure we don't rebuild the whole world needlessly.
