Very similar to the problems in I can neither open nor uninstall Steam (Ubuntu 16.04 LTS), I get this when i run "steam" in terminal:

I tried the tips to delete the links to libgcc_s.so.1 and libstdc++.so.6, and to run the command as
LD_PRELOAD='/usr/$LIB/libstdc++.so.6' DISPLAY=:0 steam
to no avail.
Also, just tried
sudo apt-get install steam:i386
based on a small aside tip about 16.10 in a thread about 16.04, same errors after install.
Have you tried the solution found here - post #6: https://forum.manjaro.org/t/cannot-start-steam/1677
