- FreeBSD removed big-endian arm with 12.0.
- OpenBSD never had big-endian arm support. I added it just in case, but it has never been used.
- Remove sparcel bits. It was sprinkled in a few places but it will never be a thing.
- Remove 32-bit sparc bits for FreeBSD. FreeBSD has never had 32-bit sparc support.
