/lib/i386-linux-gnu/ld.so.2 would be fine for x86.

It is possible, but complicated. In the example, kernel starts the alpha
emulator, then the emulator looks for the interpreter requested by the
program. A prepared system does not ship the traditional alpha/x86
interpreter, then the emulator looks for the alpha multiarch
interpreter. Otherwise, if the traditional x86 interpreter is installed,
the user must tell the alpha emulator to ignore that interpreter.
