Yes, but actually I think simple Elf loading of fully-linked images is
very easy so perhaps we should just do that in all cases.

Does NetBSD expect any special parameters when you jump into the OS
image? I'm wondering whether it is possible to eliminate all
differences between linux_build and netbsd_build. If not we can just
keep separate function calls, or have a 'guest_build' which accepts an
'OS type' argument.
