At least on Debian and openSUSE, compilers for most kernel architectures are available as cross-compilers ready for installation. So it might be a good idea to have a machine running Debian or openSUSE around for performing these tests. On Debian, you can just install a SPARC compiler with: $ apt install gcc-sparc64-linux-gnu The only target that is currently missing is ia64 but that's on my TODO list for Debian :). Adrian -- .''`.
