dmd: can't build on Arch Linux or latest Ubuntu

[Atila Neves via Digitalmars-d]

I can't build dmd on Arch Linux anymore. I'm told it's because of 
a binutils update. Annoying.

So I went "I know, I'll just use a container". I tried Ubuntu 
Zesty in docker. That doesn't build dmd off the bat either, it 
fails with PIC errors.

I'm using Trusty, and that works. But... it's a matter of time 
before most people are on newer versions of everything and dmd 
won't be buildable on Linux.

Maybe add newer distros on the autotester?
