It's currently done this way, ld-linux.so looks in a special "686" path when the ELF vector mentions it, otherwise normal path. There is a special 686 version of glibc and linuxthread. Just it's a very complicated and disk space chewing solution for a simple problem (some distributions are starting to drop support for 386 because of that)
