FWIW, buildroot now has the ability to build a complete cross build environment (I've used ARM and PowerPC). This is a configuration option: buildroot's cross or an external cross build environment. Buildroot does the Right Thing: all the required host-, target- and cross- tools need to live inside the same tree. This includes the option to build lib_.a (non-shared) cross libraries on the host, statically link against them for the target executable, and only install the target executable on the target installation (no carrying lib_.a baggage on the target file system). I've created a couple of simple buildroot packages and it was nearly trivial. The buildroot preference is touse cmake for the package build support - I went with that and was very happy with the level of effort required (low!).
