Current biarch packages like libc6-i386 do *not* install a symlink for
ld.so so there is no conflict.

However, the maintainer scripts for the various x86 libc packages are
doing a lot of conditional changes to symlinks and directories to make
coinstallation and upgrades work properly.  You should ask the glibc
maintainers <[email protected]> how this works for x86 and
how it could translate to mips.
