Yes, it's Ubuntu 14.04

 $ uname -a
Linux john-Precision-WorkStation-T3400 3.13.0-49-generic #83-Ubuntu SMP Fri
Apr 10 20:14:51 UTC 2015 i686 i686 i686 GNU/Linux

I tried creating an empty ld-linux.so.2 in /usr/lib/gcc/i686-linux-gnu/4.8/
and also in /home/mudd/musl/musl-1.1.8.install/lib/. I'm not sure if either
is what Szabolcs Nagy suggested but neither seemed to make a difference.
