Yes, that should work. I haven't tried a pure x86 userland, so I can't
claim that everything works, there may be some nits in the compat_netbsd32
One thing that does not work, unfortunately, is native pthreads.
The SA code copies structures to and from userland, and these structures
contain addresses, which have a different size. This needs to be fixed.
