When using multi-stage builds, we would like support cross-compilation. Example is 2-stage build when the first stage is compiled for host while the second stage is compiled for the target. Normally, the second stage would be also used for compiling runtimes, but that's not possible when cross-compiling, so we use the first stage compiler instead. However, we still want to use the second stage paths. To do so, we set the -resource-dir of the first stage compiler to point to the resource directory of the second stage. We also need compiler tools that support the target architecture. These tools are not guaranteed to be present on the host, but in case of multi-stage build, we can build these tools in the first stage.
