Missing 32-bit lwjgl for lwjgl-3.1.2-natives-linux.jar

My Minecraft won't start up the 1.13-pre1 snapshot. On 32-bit Ubuntu Linux, it cites a missing liblwjgl32.

A 64-bit Ubuntu runs 1.13-pre1 fine (starts, displays menu, creates and loads world).

file liblwjgl.so:
/home/viking/.minecraft/libraries/org/lwjgl/lwjgl/3.1.2/liblwjgl.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=d91e73d2dbbd37b323f304fbd8627f203d9acc36, stripped

As you can see, there's no 32-bit library to link, causing Minecraft to terminate at the linking stage.

I hope this helps you out. We'd really really like a 32-bit compatible linux lwjgl to use, as I won't be upgrading this machine for a while yet.
