Hi Doug!

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 :).
