Primitive example of what I think I should base my patchset on.  Its
invasive and large.

https://github.com/seanbruno/qemu-bsd-user/tree/merge1

That branch, is all the bsd-user changes that are pending in one large
"splat".  It excludes the new architectures (arm, aarch64, mips, mips64)
that we are actively using.  i386-bsd-user when compiled statically on
x86_64 will run a static (rescue) sh ... so, I think that's good.
x86_64 running on x86_64 just blows up.

As for sparc/sparc64 ... I'm tempted to delete them as nobody in freebsd
is actively maintaining them nor do we have any expectation that they
will work someday.
