Comment:
For the normal case, don't run this conditionally, and always use `usr/lib`.

What you can do to cater to (current) multilib setups is detect if `usr/lib32` is a directory and `usr/lib32/gconv` exists, and then run iconvconfig for it as well, assuming it behaves correctly (which it should, glibc is full of workarounds for every thing).
