cross-building for a vax, from a solaris x86 machine,
using gcc 4.3.3

>Description:
Since I spent a bunch of time getting gcc 4.3.3 to run
as a cross-compiler in the netbsd tree, I figured I'd
see if it could work for something other than a coldfire.

I picked the vax, since I know its support in gcc is,
um, a little weak.

Anyway:
