afaik, it's what NetBSD does.  In order to use NetBSD's emulation with
dynamic binaries, you typically need the native ld.so and lib*.so 
library files installed in /emul/whatever.

It's probably a good idea to have an /emul directory for every
emulation.  It provides all kinds of flexibility to work around
platform-specific ideosyncracies.
