Well when I run it at the command line it works okay, but under lit has 
this problem.

The first level compiler (which has a different set of .so's and 
libraries) works okay.
This compiler is built on linux using clang/llvm but with a different 
supporting toolchain and libs than are on the actual box.

Then the second level compiler is built on the mips box and everything 
else seems fine, except for these two tests.

This could just be a difference between supporting libs and such.
