lib32asound2 looks for plugins in obsolete /usr/lib32 location

In Precise, lib32asound2 looks for plugins in /usr/lib32/alsa-lib, but they are no longer there. The 32-bit plugins are provided by libasound2-plugins:i386 and are in /usr/lib/i386-linux-gnu/alsa-lib. Thus any program using the 32-bit libasound binary from lib32asound2 will fail to load any plugins (e.g., pulse).

This breaks sound for any program that loads the lib32asound2 binary, e.g. the HIB game Lone Survivor. (Curiously though, after removing and re-installing lib32asound2, it loads the libasound2:i386 binary instead.)

Since lib32asound2 is obsoleted by libasound2:i386, some sort of upgrade path to remove it is needed.
