You don't, but the Linux community does build for those
architectures. Most people do tree wide refactoring work using
x86. Tree wide cleanups using x86, etc. Any changes like that could
touch your driver. The harder is it to build, the less build testing
it will get, and tree wide changes which break it are less likely to
get noticed.  So you really do want it to compile cleanly for all
architectures. If it does not, it normally actually means you are
doing something wrong, something you need to fix anyway. So please do
build it for x86 and make sure it builds cleanly.
