play.rust-lang.org online compiler playground broken, returns "error: linking with cc failed"

No matter what code is used, evaling is broken. Also impacts http://www.rust-lang.org/ homepage demo as well. Didn't happen yesterday.

I was aware of this problem and had frozen it at the last good nightly. The problem now exists on master again. I don't think it's a problem in Playpen or the wrappers here.

[alexcrichton]

Regardless, this is still a bug with the current state of playpen, so I'm going to reopen this to track the fix.

[thestinger]

This is fixed.
