That link should work as long as it does not clash with the real dynamic
loader. Since you are using an Android, it should not happen. In my Android
phone the dynamic loader is "/system/bin/linker" and the "/lib" directory
doesn't even exist.

AFAIK, there is no way to change the embedded dynamic linker when running
the executable directly. Maybe some trick with the "binfmt_misc" could do
the trick but I don't think it is enabled on Android.

If you really need this, you may have to resort to change every program in
the chroot for a script that does the magic needed.

Now what really intrigues me is why you want to call a chroot'ed program
from outside of the chroot...
