branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.08.x
Checking for the existence of the dtc binary built by the
non-dependent dtc package may cause instable behaviour when giving more
freedom on the order of how the packages are built (parallelization).
In addidion, when moving to per-package host/target method, the check
would always trigger in the isolated host, leading to linux-dtc always
being installed as dtc.
This in turn may lead to undesired overwriting of the real host-dtc binary
when finally assembling the global host dir.
Thus rework the linux-dtc install condition to be defined by configuration
rather than compile time order.
