The issue is that it is linked against host and NetBSD libc so there would
be symbol collisions.
The way it works now is to resolve all NetBSD symbols except the syscalls
but this is not so easy in the dynamic case.
I think it is possible though. That was why I was working on static linking
before. It might require a custom host toolchain.
