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)
