My reading of https://wiki.debian.org/Multiarch/Implementation is that /lib and /usr/lib don't exist a full multi-arch world. I assume they're still around on x86 because the transition to multiarch is still ongoing and some packages still expect to install their libs there. I'd prefer to avoid adding it since it could cause trouble if anyone actually created a multilib sysroot with non-wasm libs in /lib.
