LinuxGSM: ERROR: ld.so: object '/usr/lib/coreutils/libstdbuf.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.

Im am making this issue related to the following error as a couple of people are confusing it with other errors they are getting.

ERROR: ld.so: object '/usr/lib/coreutils/libstdbuf.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.

To summarise. This issue occurs because stdbuf is 64-bit and SteamCMD is 32-bit. This means stdbuf does not work with SteamCMD on 64-bit systems.

ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/coreutils/libstdbuf.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.

I have tested this and confirmed stdbuf does fail on x64. However should work on x86. unbuffer does however work. Ideally stdbuf working with 64-bit apps would be great however its up to the distro maintainers to fix.
