Good one.  I've been thinking, though: would it be possible to make
EMUL_AOUT (and, possibly, the other EMUL_* options) tweakable as to
the kind of directory search mechanism they provide?  If you could
choose between:

 - searching only /emul/... (sort of an /emul jail)
 - searching only /... (requiring ld.so to check /emul/...)
 - searching /emul/... first, then /... (current behavior)
 - searching /... first, then /emul/...
 - searching a union of /emul/... on top of /... (like unionfs)

...well, I think that could be useful.  Possibly not sufficiently so
to warrant the work, but useful.  And kind of cool.  :-)
