Lets say that /emul/foo/usr/lib is a symlink to /lib and I'm running a
program in emulation foo.
What do I get when I:
1) opendir /usr/lib
2) cd to /emul/foo/usr and opendir ./lib
3) opendir /emul/foo/usr/lib
   (assuming /emul/foo/emul/foo doesn't exist)
4) A non-emulation program opens /emul/foo/usr/lib

For the first 2 the desired effect has to be to open /emul/foo/lib.
The latter 2 are non-obvious!
