Steam won't start on Ubuntu 16.04 LTS 64-bit with AMD GPU

Steam on Ubuntu 16.04

I run two PC's with AMD GPU's and with the release of Ubuntu 16.04 LTS, I have been unable to run steam using the default grpahics drivers that come with steam. Clicking the steam icon, just made it flash for a little bit, but steam never started. To get more detail, I tried running steam from the command-line, and I got the following error message:

jordan@jordan-H8DI3:~$ steam

I had to hit CTRL+C in order to get out of it. After some research, I was able to get steam running with the following command:

LD_PRELOAD='/usr/$LIB/libstdc++.so.6' DISPLAY=:0 steam

I haven't tried a lot of games through steam after starting this way, but the ones that I did try have run just fine... so far.
