Those i386 libraries on amd64

[Lloyd Parkes <lloyd%must-have-coffee.gen.nz@localhost>]

So I found all those i386 libraries in /usr/lib/i386 on my amd64 system and I 
found them really handy because I had just converted it from an i386 system and 
I hadn't  prepared some of my apps as well as I should have. 

Where do those libraries come from? I've had a look, but it's buried deeper 
than I have the energy to dig at the moment, and it would be nice if someone 
could just tell me the answer. 

There is a bug in the Citrus I18N library such that when this special i386 
build is done, it doesn't know that it should use the new library path when 
trying to dlopen() modules that it wants and it tries loading a 64 bit library 
into a 32 bit program. This is a bug that all module loading software has when 
built this way, at least NetBSD does actually seem to supply all the right 
libraries.

Once I know how these libraries get built, I hope to be able to propose a 
possible solution and then PR it.

Cheers,
Lloyd
