Still waiting for a patch from the ARM team to add support.
Doesn't build on aarch64 either. I suggest to ExcludeArch both.

Patch for rawhide
I am really not sure this package makes sense on any arch except x86
I pulled in a patch from Debian to fix the ftbfs
aarch64 still needs to be ExcludeArch'd due to missing <sys/io.h>.
