This is just the time for host-dtc. 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.
