Binary relocatability part 1

I realised last night the patch I sent in was incomplete anyway, I 
missed the changes to wineprefixcreate. Oops.

Still, I'm not sure why this has to be so generic. I think not people 
modify the standard install layout, and if they do, they probably don't 
care about binary relocatability. Why do we have to make the code so 
very complex to make it work for 100% of people when much simpler code 
could work for 95%? When do the costs outweigh the benefits?

There's another issue: I'm not sure what you're asking me to do :( Do 
you mean if somebody does, eg

./configure --bindir=a/b/c --libdir=x/y/z

that the rpath is set to

${ORIGIN}/../../../x/y/z ?

If so got any tips for how to implement this?
