Yes, you likely need both 64-bit and 32-bit LLVM and Mesa. 32-bit 
libraries are needed for Steam itself but some games launched from Steam 
seem to use 64-bit ones.

For this reason, I am now actually building both 64-bit and 32-bit 
versions for our Linux distro, ROSA.

I do not know whether it is possible to get away with only 64-bit 
versions somehow.

By the way, many thanks to Marek Olšák for the build instructions!

Regards,
Evgenii
