First round of VAX patches. This isn't complete right now, there are for

sure still bugs (properly hidden, of course), a libm is completely missing
(I've got one that implements some basic stuff, but that's really not
ready for checking in...)

I've also got a list of other things that need touch-ups, but that's mostly
minor stuff that'll be done during the next days.
