The kernel is a 32bit, hardware is 64 bit and userland is sparc instead
of sparc64 (so 32bit too).

This is similar to installing the i386 sets + kernel on an amd64
machine (but a plain sparc GENERIC kernel would not support the 64bit
hardware).

You can get very similar effect when installing a GENERIC kernel (so 64bit
kernel) but still using sparc userland, but in that setup everything
goes via compat_netbsd32 (and sometimes there are bugs that cause minor
unwanted differences between the two setups).
