As someone pointed out, there is a free VAX emulator, simh.  Both
NetBSD and Linux are ELF targets and simh does boot NetBSD/vax.
Note that testsuite submission was by me.  I can actually build and
run a NetBSD/vax ELF userland (non-shared) using GCC 3.3.x.

On and off, I've been working on improving the GCC VAX support but
time limitations have limited my efforts.

I've love to rewrite the backend but it's currently beyond my current
abilities in gcc.  I have changes to the backend in my tree but
problems with the compiler (pre-changes) limits my ability to test
them.

The VAX is not dead and there's no reason to turn off life-support
equipment.
