Split up the toolchain configuration into two phases, generic and target. The 'generic' phase configures the toolchain just enough to be able to preprocess DT files. The 'target' phase completes the configuration with target-specific configuration. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>
