Well, if you can't call getcwd, then it won't work... (I was not
suggesting that the getcwd call be wedged inside namei)

We'll probably end up doing it on every exec, since there's currently
no way to tell from the ELF headers whether $ORIGIN needs to be set
(this should be considered a bug) but failure is ok for that. In
compat_svr4 I doubt anyone cares much if it fails in corner cases.
