Replace CI_SYSTEM_NAME and CI_MACHINE_NAME with CI_HOST_SYSTEM and CI_HOST_MACHINE, respectively. Introduce CI_TARGET_SYSTEM and CI_TARGET_MACHINE, defaulting to CI_HOST_SYSTEM and CI_HOST_MACHINE, respectively. Use CI_TARGET_SYSTEM and CI_TARGET_MACHINE in the naming scheme of target build and install directories, in order to allow concurrent verification builds for multiple cross-platform targets.
