It depends on the system. For instance, on os x you can just use the -m32 flag in gcc when compiling. But shared libraries on os x are generally 'fat' and support multiple architectures which simplifies linking and loading. On linux, it's more complicated. It depends on the system. The last time I had to do this I needed to build a chroot environment to compile in. It might be easier these days. The debian amd64 faq has some approaches you can take. But it could also be out of date a bit. It's at least a starting point. http://wiki.debian.org/DebianAMD64Faq See the "Q: How do I build i386 debs on AMD64?" For actually running the apps you probably want to check out the ia32 section here http://www.debian-administration.org/articles/534
